Description

Technical Field

[0001] This invention belongs to the field of project management technology, specifically relating to a method for intelligent synchronization of front-end and back-end status information in project management. Background Technology

[0002] In the current era of accelerated digital transformation, enterprises are placing unprecedented demands on the efficiency and accuracy of project management. Modern enterprise project management systems generally adopt a "front-end-back-end" separation architecture: the front-end system is geared towards frontline operators (such as project executors and customer service personnel), providing functions such as project status viewing, basic operation execution, and data entry; the back-end system is geared towards management personnel (such as project managers and operations managers), providing core functions such as project process configuration, access control, data statistical analysis, and decision-making instruction issuance. The two systems must work together to ensure consistency of status data throughout the entire project lifecycle in order to support efficient enterprise decision-making and business implementation.

[0003] However, existing project management systems have many technical flaws in their front-end and back-end status synchronization solutions, which have become a key bottleneck restricting the efficiency of enterprise project management. These flaws are manifested in the following three aspects:

[0004] 1. State loss issue during cross-system switching

[0005] In the existing system, the project status of the front-end system is mostly stored in the browser memory. When the user switches between multiple projects, refreshes the page, or closes and reopens the browser, the status data in memory will be cleared, resulting in "state loss".

[0006] 2. Changes in backend status do not immediately affect the frontend.

[0007] Existing systems often use either "front-end periodic polling" or "user-initiated refresh" methods for front-end and back-end synchronization: the front-end system queries the back-end system for project status via HTTP requests at fixed intervals, or users need to manually click the "refresh" button to get the latest status. This approach has significant "synchronization delays." When critical status changes occur in the back-end system (such as project progress adjustments, permission changes, or approval result issuance), the front-end system cannot detect them in real time, which may lead to front-line operators performing incorrect operations based on outdated data.

[0008] 3. Data conflicts caused by parallel operations require manual intervention.

[0009] When multiple users (or front-end and back-end systems) perform parallel operations on the same status field of the same project, the existing system lacks an effective conflict detection and resolution mechanism, which can easily lead to "data overwriting" or "data corruption".

[0010] In summary, existing project management system front-end and back-end state synchronization solutions have significant shortcomings in the three core dimensions of "state persistence," "real-time synchronization," and "automated conflict resolution," failing to meet enterprises' needs for "efficient, accurate, and low-intervention" project management. Therefore, there is an urgent need for an intelligent synchronization method that can achieve "zero state loss during cross-system switching, millisecond-level response to back-end changes, and automatic conflict resolution" to address the deficiencies of existing technologies and improve the automation level and decision-making accuracy of project management. Summary of the Invention

[0011] To address the shortcomings of existing technologies, this invention provides a method for intelligently synchronizing front-end and back-end status information in project management, ensuring no loss of project status during status switching, real-time front-end response to back-end status changes, automatic conflict resolution, and no need for manual intervention.

[0012] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0013] The method for intelligent synchronization of front-end and back-end status information in project management includes the following steps:

[0014] S1. Construct a three-tier architecture consisting of a front-end system, a status storage center, and a back-end system. The front-end system is used to receive user operations and display project status. The status storage center is used to store project status data, manage status versions, and handle synchronization logic. The back-end system is used to execute project management decisions and process control.

[0015] S2. State Initialization: The front-end system obtains the unique identifier project ID of the target project through routing parameters, and then persists the initial state data of the project to the local IndexedDB database of the front-end system. The back-end system reads the initial state data in the IndexedDB database through a preset API interface, and completes the state initialization of the back-end system environment.

[0016] S3. The state synchronization between the front-end system and the back-end system is achieved through at least one synchronization method, including back-end driver synchronization or timed task synchronization.

[0017] S4. Construct a version control and conflict resolution mechanism. When the status of each project is updated, both the front-end system and the back-end system carry a version number. When submitting an update, verify the consistency between the client version number of the front-end system and the server version number of the back-end system. If they are consistent, execute the status update and increment the version number. If they are inconsistent, it is determined to be a data conflict. Automatically execute the preset conflict resolution strategy, generate and store the status data after conflict resolution, and broadcast the resolution result to the front-end system and the back-end system.

[0018] Preferably, the background driver synchronization in S3 includes:

[0019] When a project status change occurs in the backend system, the backend system generates a status change message and publishes the status change message to the RabbitMQ message queue. The frontend system listens for the corresponding message in the RabbitMQ message queue through a preset listening mechanism. After receiving the status change message, the frontend system updates the project status data in its local IndexedDB database and triggers the frontend system's UI components to automatically render and update based on the responsive framework.

[0020] Preferably, the timed task synchronization in S3 includes:

[0021] The front-end system and the back-end system establish a long connection via WebSocket. The back-end system's scheduled task process monitors changes in the project status in real time. When an incremental update to the project status is detected, the back-end system generates an incremental data packet containing the changed fields and pushes it to the front-end system through the WebSocket long connection. The front-end system parses the incremental data packet and updates the status of the corresponding components in real time.

[0022] Preferably, the automatic rendering of the UI components of the front-end system adopts a Vue or React reactive update mechanism.

[0023] Preferably, the conflict resolution strategy in S4 adopts the latest state of the backend system server or is extended to a custom conflict resolution strategy.

[0024] Preferably, in step S4, the consistency between the client version number of the front-end system and the server version number of the back-end system is verified using MD5 matching.

[0025] Preferably, risk management steps are also included:

[0026] Real-time operation logs are used to synchronously monitor the entire process of operation. When an abnormal status change is detected, an alarm is automatically triggered, and the operation scene is restored by tracing the status version.

[0027] By adopting the above technical solution, the present invention has the following beneficial effects:

[0028] (1) This invention realizes local persistent storage of project status in the front-end system through the IndexedDB database. The IndexedDB database has the characteristics of large storage capacity, support for complex JSON data, data persistence, and no data loss after browser restart. It solves the problem of state loss caused by existing systems relying on memory storage. After users switch between multiple projects, refresh the page or restart the browser, the front-end system can directly read the latest status of the corresponding project from the IndexedDB database without having to request data from the back-end system again, thus achieving zero state loss when switching between systems and improving the continuity of operation.

[0029] (2) This invention adopts a dual-channel synchronization strategy of “RabbitMQ message queue combined with WebSocket long connection” to replace the traditional timed polling scheme. The RabbitMQ message queue is used for real-time push of full state changes in the background. The average delay of the message from the background system to the front-end system is low, much lower than the delay of timed polling, ensuring that key changes in the background system reach the front-end quickly. The front-end responds to the background state changes in real time, ensuring data real-time performance. The WebSocket long connection is used for push of incremental state updates in the background. The incremental data contains changed fields, and the data volume is small, reducing network bandwidth usage. At the same time, the “full-duplex” communication mode of WebSocket supports active push from the background, eliminating the need for frequent requests from the front-end system and reducing server load.

[0030] (3) The present invention has a version control and conflict resolution mechanism. In specific applications, it can automatically detect and resolve data conflicts caused by parallel operations, realize automatic conflict resolution, and reduce the cost of manual intervention.

[0031] In summary, this invention has the advantages of no loss of project status during switching, real-time response of background status changes to the front end, and automatic conflict resolution without manual intervention. Attached Figure Description

[0039] Example 1

[0040] In this embodiment, a method for intelligent synchronization of front-end and back-end status information in project management is proposed. This method aims to solve the problems of information asynchrony and confusion in the prior art, which leads to misjudgment, delays, and resource waste, as well as the confusion of front-end project information caused by simultaneous operation of multiple projects. Through the technical solution of this invention, real-time, automatic, and reliable synchronization of project status between the front-end and back-end management systems can be achieved, ensuring the uniqueness of the data source and global consistency, thereby significantly improving the automation level, operational efficiency, and decision-making accuracy of the project management process.

[0041] like Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the intelligent synchronization method for front-end and back-end status information in project management includes the following steps:

[0042] S1. Construct a three-tier architecture consisting of a front-end system, a state storage center, and a back-end system. The front-end system receives user operations and displays project status. The state storage center stores project status data, manages status versions, and handles synchronization logic. The back-end system executes project management decisions and controls processes. Specifically, this invention abandons the limitations of the traditional two-tier "front-end-back-end" architecture of project management systems and innovatively designs a three-tier architecture of "front-end system - state storage center - back-end system," clearly defining the functional positioning and interaction logic of each layer, providing stable and efficient basic support for status synchronization.

[0043] Front-end system: Designed for frontline operators, its core functions include:

[0044] (1) Receiving user operations: Supports users to initiate operations such as querying, modifying, and submitting project status (e.g., editing project progress, adjusting product inventory, marking task status, etc.);

[0045] (2) Display project status: Visualize the real-time status of the project through UI components (such as data dashboards, progress bars, detail cards, etc.) to ensure that users can intuitively obtain information;

[0046] (3) Local state persistence: The initial state and updated state of the project are stored in the IndexedDB database. As a local database on the browser side, IndexedDB has the advantages of offline storage, large capacity (no fixed storage limit, dependent on device storage space) and support for transaction operations, which can avoid the loss of state caused by page refresh or system switch.

[0047] (4) Synchronous response and UI rendering: Receive synchronization instructions from the state storage center or the backend system, update the local storage state, and trigger the automatic rendering of UI components based on the Vue or React reactive framework to achieve seamless page refresh.

[0048] State Storage Center: As the "central node" for front-end and back-end state synchronization, its core functions include:

[0049] (1) Project status data storage: Centrally store the current status data of all projects (such as basic project information, progress data, resource configuration, version number, etc.) to ensure the uniqueness of the data source;

[0050] (2) Status version management: Assign a unique version number to each project status update, record the version change history, and support version tracing and rollback;

[0051] (3) Synchronization logic processing: Receive synchronization requests from the front-end and back-end systems, parse the request content (such as status change fields, version numbers), and trigger the corresponding synchronization mechanism (back-end driver synchronization or scheduled task synchronization).

[0052] (4) Conflict resolution execution: When a data conflict is detected, the preset conflict resolution strategy is invoked to generate the resolved status data and broadcast the result to the front-end and back-end systems;

[0053] Back-end system: geared towards management decision-making and process control, core functions include:

[0054] (1) Project management decision-making: Support managers in configuring project processes (such as approval nodes and permission allocation) and issuing management instructions (such as adjusting project priority and suspending projects);

[0055] (2) Process control execution: Automatically execute project processes according to preset rules (such as triggering the approval process when the approval conditions are met, and triggering a replenishment reminder when the inventory is below the threshold).

[0056] (3) Status change monitoring: Real-time monitoring of project status changes caused by background operations, generating change messages or incremental data packets;

[0057] (4) Synchronization command initiation: The state change information is pushed to the state storage center or the front-end system through a message queue or long connection to trigger the synchronization process;

[0058] The interaction logic of the three-tier architecture is as follows: the front-end system and the back-end system do not interact directly with each other. All state synchronization requests are forwarded and processed through the state storage center. The state storage center uniformly manages data storage and version control to ensure that the state data obtained by the front-end and back-end systems comes from the same source, thus ensuring data consistency from the architectural level.

[0059] After constructing the three-tier architecture, the next step is state initialization. State initialization is the foundation for front-end and back-end synchronization, aiming to ensure that the initial states obtained by the front-end and back-end systems are consistent when the project starts. Specifically, S2, State Initialization: The front-end system obtains the unique identifier project ID of the target project through routing parameters, and then persists the initial state data of the project to the local IndexedDB database of the front-end system. The back-end system reads the initial state data in the IndexedDB database through a preset API interface, thus completing the state initialization of the back-end system environment.

[0060] More specifically, when a user opens a target project in the front-end system (e.g., clicks on "Product A Project" or "Software Development Task 1"), the front-end system parses the project's unique identifier—the project ID—through URL routing parameters. Based on the project ID, the front-end system requests the project's initial status data from the status storage center (the initial status data includes basic project information such as project name, responsible person, creation time, and business status data such as product price, inventory, and task progress). After receiving the initial status data, the front-end system persists it to the local IndexedDB database, with the storage structure using the project ID as the key and the status data (…). The initial version number (starting from "1" by default) is used as the value to ensure that the state can be read directly from the local system when the page is refreshed or the system is switched, without the need for repeated requests. The backend system sends an initialization request to the state storage center through a preset API interface, carrying the target project ID in the request. After verifying the validity of the request (such as backend system permissions and project ID validity), the state storage center returns the initial state data of the project to the backend system. After receiving the initial state data, the backend system loads it into its own project management environment (such as backend database and cache system) to complete the state initialization and ensure that the initial state of the project in the backend system is consistent with that in the frontend system.

[0061] Through the above initialization process, the front-end and back-end systems establish a unified state baseline during the project startup phase, laying a data consistency foundation for subsequent synchronization operations.

[0062] After the state initialization is completed, the present invention adopts a dual-mode state synchronization. The present invention designs two synchronization modes: "background driver synchronization" and "timed task synchronization", which can be used alone or in combination to meet the real-time requirements of different business scenarios.

[0063] Specifically, S3, the state synchronization between the front-end system and the back-end system is achieved through at least one synchronization method, including back-end driver synchronization or scheduled task synchronization;

[0064] The background driver synchronization in S3 includes:

[0065] When a project status change occurs in the backend system, the backend system generates a status change message and publishes the status change message to the RabbitMQ message queue. The frontend system listens for the corresponding message in the RabbitMQ message queue through a preset listening mechanism. After receiving the status change message, the frontend system updates the project status data in its local IndexedDB database and triggers the frontend system's UI components to automatically render and update based on a responsive framework. The automatic rendering of the frontend system's UI components adopts a Vue or React responsive update mechanism.

[0066] The timed task synchronization in S3 includes:

[0067] The front-end system and the back-end system establish a long connection via WebSocket. The back-end system's scheduled task process monitors changes in the project status in real time. When an incremental update to the project status is detected, the back-end system generates an incremental data packet containing the changed fields and pushes it to the front-end system through the WebSocket long connection. The front-end system parses the incremental data packet and updates the status of the corresponding components in real time.

[0068] In this invention, the backend-driven synchronization is suitable for scenarios with extremely high real-time requirements (such as product price adjustments, inventory changes, and urgent task status updates). When a state change occurs in the backend system, it actively triggers frontend synchronization, achieving "backend changes, frontend changes immediately." The more detailed process is as follows:

[0069] (1) Backend generates and publishes change messages: When the backend system changes the status of a project through manual operation (such as the operation modifying the product price) or automatic process (such as the system detecting that the inventory is lower than the threshold), the backend system first generates a "status change message". The message content includes: project ID (identifying the project to which the change belongs), changed fields (such as "price: 299→199" "inventory: 100→95"), change time, and current server version number;

[0070] (2) The backend system publishes the status change message to the RabbitMQ message queue (RabbitMQ, as a mature message middleware, has the advantages of high reliability and high throughput, which can ensure that messages are not lost or duplicated), and marks the message with a unique "queue identifier" (such as using the project ID as the queue name to ensure that the frontend system can accurately listen to the change message of the target project).

[0071] (3) Front-end listens for and processes change messages: When the front-end system starts, it establishes a connection with the RabbitMQ message queue through a preset listening mechanism (such as based on RabbitMQ client SDK) and subscribes to the "queue identifier" corresponding to the target project;

[0072] (4) When a status change message for the project appears in the RabbitMQ message queue, the front-end system immediately receives the message and parses the change field and version number in the message;

[0073] (5) The front-end system updates the status data of the corresponding project in the local IndexedDB database based on the parsing results (only the changed fields are updated, without overwriting all data, thus reducing local storage overhead).

[0074] (6) Automatic rendering and updating of UI components: The UI components of the front-end system are developed based on the Vue or React reactive framework. When the state data in IndexedDB changes, the reactive framework automatically detects the data change and triggers the corresponding UI components to re-render. For example, the "price tag" component on the product details page is automatically updated to the new price, and the "progress bar" component on the task progress page is automatically adjusted to the new progress. The whole process does not require the user to manually refresh the page, achieving "millisecond-level response".

[0075] Scheduled task synchronization is suitable for scenarios with lower real-time requirements but need to continuously monitor status changes (such as slow project progress updates or adjustments to non-core fields). By monitoring incremental changes in the background on a scheduled basis, it reduces the transmission of full data and lowers system bandwidth consumption. The more detailed process is as follows:

[0076] (1) Establishing a WebSocket long connection: After the front-end system starts, it establishes a long connection with the back-end system through the WebSocket protocol (WebSocket supports bidirectional communication and the connection remains persistent, avoiding the frequent handshake overhead of traditional HTTP short connections). When the connection is established, the front-end system sends the target project ID to the back-end system to identify the scope of projects that need to be synchronized.

[0077] (2) Background periodic monitoring of status changes: The background system deploys a periodic task process (the periodic period is configurable, such as 1 second / time, 10 seconds / time, which can be adjusted according to business needs). This process periodically queries the current status of the target project in the status storage center and compares it with the status of the last monitoring.

[0078] (3) If the comparison finds that the project status has been updated incrementally (i.e. only some fields have changed, rather than the entire status has changed), the backend system generates an "incremental data packet". The data packet content includes: project ID, incrementally changed fields (such as "inventory: 95→90"), current server version number, and data packet generation time. If no change is found, no data packet is generated to avoid invalid transmission.

[0079] (4) Background push incremental data packets: The background system pushes incremental data packets to the front-end system through the established WebSocket long connection. Since the incremental data packets only contain changed fields, the data volume is much smaller than the full state data, which can significantly reduce network bandwidth usage and improve synchronization efficiency.

[0080] (5) Front-end parsing and updating component status: After receiving the incremental data packet, the front-end system parses the change fields and version number in it, and updates the status data of the corresponding project in the local IndexedDB database;

[0081] (6) The front-end system locates the corresponding UI component and triggers the update based on the type of the changed field: for example, if the changed field is "inventory", only the "inventory display" component and the "inventory warning progress bar" component are updated; if the changed field is "project leader", only the leader information in the "member management" component is updated, thus avoiding performance loss caused by full-page rendering.

[0082] This invention adopts a dual-mode design of "background-driven synchronization + scheduled task synchronization" to flexibly adapt to different business scenarios. For core business fields (price, inventory, urgent task status), background-driven synchronization is used to ensure real-time performance, while for non-core fields (project notes, non-urgent progress), scheduled task synchronization is used to balance efficiency and resource consumption.

[0083] Version control and conflict resolution are the core of ensuring data consistency between the front end and the back end. Through version number verification and preset strategies, conflicts caused by parallel operations are automatically identified and handled.

[0084] Specifically, S4 establishes a version control and conflict resolution mechanism. When the status of each project is updated, both the front-end system and the back-end system carry a version number. When an update is submitted, the consistency between the client version number of the front-end system and the server version number of the back-end system is checked. If they are consistent, the status update is performed and the version number is incremented. If they are inconsistent, it is determined to be a data conflict, and a preset conflict resolution strategy is automatically executed. The conflict resolution strategy adopts the latest status of the server of the back-end system or extends it to a custom conflict resolution strategy. The consistency between the client version number of the front-end system and the server version number of the back-end system is checked using the MD5 matching method. After the conflict resolution strategy is executed, the status data after conflict resolution can be generated and stored, and the resolution result is broadcast to the front-end system and the back-end system.

[0085] Continue to refer to Figure 2 The specific implementation method of the version control and conflict resolution mechanism of the present invention is as follows:

[0086] (1) Version number management: Whether it is a status update initiated by the front-end system (such as a user modifying the project progress) or a status update initiated by the back-end system (such as the operation adjusting the product price), when submitting an update request, the "version number" of the current operation must be included. When submitting from the front-end, the "client version number" (the current version from the local IndexedDB storage) is included, and when submitting from the back-end, the "server version number" (the current version from the status storage center) is included. The version number adopts the form of "incrementing integer" (such as 1→2→3…). After each successful status update, the version number is automatically incremented by 1. The version number is bound to the project ID. The version numbers of different projects increment independently to avoid cross-project version confusion.

[0087] (2) Version consistency verification (MD5 matching): When the backend system submits a status update request to the status storage center, the status storage center first extracts the project ID "client / server version number" in the request and obtains the "current latest version number" of the project from its own storage. The status storage center uses the MD5 hash algorithm to match the version number in the request with the latest version number in its own storage: convert the two version numbers into MD5 hash values ​​respectively. If the two hash values ​​are completely consistent, the versions are determined to be consistent. If they are inconsistent, the versions are determined to be inconsistent and there is a data conflict. The MD5 matching method has the advantages of "uniqueness" and "efficiency". The MD5 hash values ​​corresponding to different version numbers are absolutely different, which can accurately identify version differences. At the same time, the MD5 calculation speed is fast and will not increase the system processing delay.

[0088] (3) Conflict resolution strategy: If the MD5 matching result shows that the versions are consistent, it means that there is no conflict in the current operation. The state storage center performs the following steps: according to the change field in the update request, it updates the project state data stored in its own storage, increments the version number of the project by 1 (e.g., from "1" to "2"), and synchronizes the updated state data and the new version number to the front-end system and the back-end system through the broadcast mechanism. After receiving the data, the front-end system updates the state and version number in the local IndexedDB and triggers UI rendering. After receiving the data, the back-end system updates the state and version number in its own environment and completes the synchronization.

[0089] If the MD5 match result shows a version mismatch, it indicates a conflict arising from concurrent operations (such as a front-end user and a back-end operations team simultaneously modifying the inventory of the same project). The state storage center automatically executes a preset conflict resolution strategy. If no custom strategy is configured, the system defaults to using the "latest server-side state" as the conflict resolution result. That is, the state storage center uses its own latest stored state (server-side state) as the final state, overriding any conflicting states submitted by the front-end or back-end. Custom strategies (flexibly adaptable to business needs) allow enterprises to configure custom conflict resolution strategies based on business scenarios, such as field priority strategies, operation time strategies, role-based access control strategies, etc. The priority strategy sets priorities for different fields. In case of conflict, the higher priority field retains the status of the corresponding operation (e.g., the "price" field has higher priority than the "remarks" field; if the front-end changes the remarks and the back-end changes the price, the back-end price and the front-end remarks are retained in case of conflict). The operation time strategy retains the status corresponding to the latest operation time (e.g., if the front-end operation time is 12:00:01 and the back-end operation time is 12:00:02, the back-end status is retained in case of conflict). The role-based permission strategy sets priorities according to the operator's role. In case of conflict, the operation status of the higher-privilege role is retained (e.g., the "administrator" operation has higher priority than the "regular operator" operation; the status set by the administrator is retained in case of conflict).

[0090] The state storage center generates the final state data after conflict resolution and assigns a new version number (original version number + 1) to the state. It stores the final state and the new version number in its own database. The state storage center broadcasts the conflict resolution result (including the final state, new version number, and conflict cause) to the front-end and back-end systems through RabbitMQ message queue or WebSocket long connection. After receiving the resolution result, the front-end and back-end systems update the state data and version number stored locally, respectively. At the same time, the front-end system prompts the user through UI components that "the conflict has been automatically resolved and the current state is the latest" to ensure that the user is aware of the conflict situation.

[0091] To ensure the security and traceability of the project status synchronization process, this invention adds a risk management step. Through real-time monitoring, anomaly alerts, and version tracing, operational risks are reduced. In other words, this invention also includes a risk management step:

[0092] Real-time operation logs are used to synchronously monitor the entire process of operation. When an abnormal status change is detected, an alarm is automatically triggered, and the operation scene is restored by tracing the status version.

[0093] Specifically, the front-end and back-end systems generate an "operation log" whenever they initiate any status operation (such as query, modify, submit, or conflict handling). The log content includes: operator ID, operation time, operation type (query / modify / conflict handling), project ID, status before operation (including version number), status after operation (including version number), and operation result (success / failure). The operation log is synchronized to the "log database" in the status storage center in real time. The log database adopts an immutable design (such as storage based on timestamps and hash chains) to ensure that the log content cannot be maliciously modified. The back-end system can use the log query function to retrieve operation logs by operator, project ID, time range, and other conditions to achieve full-process operation behavior monitoring.

[0094] The state storage center deploys anomaly detection rules (which can be configured). Common rules include: detecting that an operator does not have modification permissions for the corresponding project but initiates a status change request; the same project undergoes multiple status changes within a short period of time (e.g., within 1 minute), and the change directions are contradictory (e.g., the price repeatedly changes from 299 yuan → 199 yuan → 299 yuan); and the project status jumps from "completed" to "not started" (a jump that does not conform to the preset process logic). When the state storage center detects a status change that meets the anomaly rules, it immediately triggers an alarm mechanism, including system alarms and notification alarms. System alarms refer to the generation of a red alarm prompt in the "Risk Monitoring Center" of the backend system, and at the same time, a pop-up alarm is pushed to the administrator account of the frontend system. Notification alarms are sent via email or SMS to preset risk handling personnel (e.g., project manager, system administrator), and the information content includes the abnormal time, project ID, abnormal operation details, risk level (high / medium / low), etc.

[0095] When data errors or operational accidents occur (such as accidentally deleting project status or incorrectly modifying core fields), administrators can initiate a "version traceability request" through the backend system. The request includes the target project ID and the historical version number to be traced. Based on the request, the status storage center retrieves the status data of the corresponding historical version of the project from the version database and returns it to the backend system. Administrators can preview the historical version status. If restoration is required, a "version rollback request" can be initiated. The status storage center replaces the current project status with the historical version status and updates the version number (e.g., rolling back from the current version "8" to version "6", the new version number is set to "9"). The status storage center also broadcasts the rollback result to the frontend system to ensure that the frontend and backend statuses are rolled back synchronously, realizing "operation scene restoration" and reducing the impact of accidents.

[0096] Compared to existing front-end and back-end synchronization technologies in project management systems, this invention has the following advantages:

[0097] (1) Data consistency has been significantly improved, eliminating the risk of business misjudgment.

[0098] This invention employs a "three-tier architecture + version control" design, ensuring that the state data of both the front-end and back-end systems originates from a single source—the state storage center. Furthermore, each update undergoes version consistency verification, completely resolving the existing system's issues of "information asynchrony" and "data chaos." For example, in e-commerce projects, after the back-end modifies a product price, the front-end can synchronize and update within milliseconds, preventing disputes caused by users placing orders at outdated prices. In software development projects, the real-time consistency of front-end and back-end task states allows project managers to schedule tasks based on accurate data, reducing misjudgments due to data discrepancies. Practical application verification shows that adopting this invention significantly reduces the inconsistency rate between the front-end and back-end data in the project management system.

[0099] (2) Real-time synchronization has been greatly improved, and user experience has been optimized.

[0100] The background driver synchronization is based on the RabbitMQ message queue to achieve "change-as-synchronization", which can significantly reduce the front-end response latency. The scheduled task synchronization uses incremental data packets and WebSocket long connection, which significantly improves the synchronization efficiency compared with the traditional full pull method. During the user operation, there is no need to manually refresh the page to see the latest status. For example, when the project executor is editing the task progress on the front end, the back-end administrator can see the progress changes in real time without waiting for scheduled updates. Customer service personnel can accurately answer customers "whether the goods are in stock" based on the real-time synchronized product inventory on the front end, thereby improving service quality and user satisfaction.

[0101] (3) Automated conflict handling reduces labor costs.

[0102] The intelligent conflict resolution mechanism of this invention can automatically identify and handle conflicts in parallel operations without manual intervention. Taking an e-commerce company as an example, under the existing technology, the operations team needs to spend a lot of time manually checking and handling synchronous conflicts of inventory and prices every day. After adopting this invention, the automatic conflict resolution rate is improved, and the operations team can invest this part of the time in business optimization, reducing labor costs. At the same time, the custom conflict strategy supports enterprises to flexibly configure according to business needs, adapt to the conflict handling needs in different scenarios, and improve collaborative efficiency.

[0103] (4) State persistence and seamless synchronization enhance operational continuity.

[0104] The front-end system uses IndexedDB to achieve local persistence of state. When users switch between projects or modules, state data is not lost and edited content can be restored, solving the problem of "state loss when switching between systems" in the existing system. For example, when a project executor is editing project notes on the front end and temporarily switches to another page, the notes are still retained when returning, without the need to re-enter them. After the page is refreshed, the front end directly reads the state from IndexedDB without requesting the back end again, which improves page loading speed and significantly enhances the smoothness of operation.

[0105] (5) Risks are controllable throughout the entire process, and system security is improved.

[0106] Real-time operation logs and anomaly alarm mechanisms enable "full monitoring and anomaly detection" of project status changes. Version tracing and on-site restoration functions can quickly handle data errors or operational accidents, reducing the impact of risks. For example, if an operator mistakenly changes the status of a "core project" to "paused," the system immediately triggers a high-level alarm. The administrator can restore the correct status in a short time through version tracing, avoiding the risk of project stagnation. After adopting this invention, the security incident handling time of the enterprise project management system is shortened, and the system security and reliability are greatly improved.

[0107] (6) Highly scalable and adaptable to multiple industry scenarios

[0108] The core architecture and synchronization mechanism of this invention do not depend on specific business types. They can be adapted to the project management needs of different industries by configuring custom parameters (such as synchronization cycle, conflict strategy, and alarm rules). In the e-commerce field, it can be used for product price and inventory synchronization; in the software development field, it can be used for task progress and bug status synchronization; in the logistics field, it can be used for cargo transportation status and warehouse inventory synchronization; and in the enterprise collaboration field, it can be used for team task allocation and project phase synchronization. Currently, this invention has been implemented in six types of enterprises, including clothing, home appliances, fast-moving consumer goods, and software development, and has achieved significant efficiency improvements, verifying its universality and scalability.

[0109] This invention can collect conflict data (such as fields frequently modified by users) during the state synchronization process, analyze bottlenecks in state transition (such as an approval state staying for too long), and optimize the operation process based on the state change heatmap.

[0110] This embodiment does not impose any limitation on the shape, material, structure, etc. of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the technical solution of the present invention.
