[0030] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "multiple" and "several" is two or more, unless otherwise clearly and specifically defined.

[0033] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification so as to facilitate understanding and reading by persons familiar with this technology. They are not used to limit the conditions under which the present invention can be implemented, and therefore have no substantive technical significance. Any structural modification, change in proportion or adjustment of size, without affecting the effects and purposes that can be achieved by the present invention, should still fall within the scope of the technical contents disclosed by the present invention.

[0034] Please Figures 1 to 6As shown, the cross-platform seamless data synchronization method for Hongmeng App development provided by an embodiment of the present invention includes the following steps: defining a unified data model and API interface; implementing specific adapters for OS operating system platform, Android operating system platform and Hongmeng operating system platform; using a timestamp-based incremental synchronization algorithm to update database data according to data obtained from the API interface; resolving conflicts for concurrent modifications; if an offline situation occurs, using an offline queue to assist in updating database data; the step of using a timestamp-based incremental synchronization algorithm to update database data according to data obtained from the API interface includes the steps of: setting the last modification timestamp for the modified data record; using a difference comparison algorithm to process the modified data to obtain data that is different from the most recent synchronization; processing platform-specific data type conversion and storage methods; transmitting data that is different from the most recent synchronization.

[0035] Among them, designing a standardized data model and building a unified platform-independent API interface can ensure that different platforms use the same data model to interact with data through the same interface, and reduce the difficulty of data compatibility by standardizing the data format and transmission method; through specific adapters, Hongmeng system and other mainstream platforms can interoperate and synchronize data under different storage models and data formats; the incremental synchronization method used when transmitting data is a method that only synchronizes changed data, reduces redundant data transmission, optimizes network bandwidth, improves synchronization speed, and reduces user waiting time. Conflict resolution is performed for concurrent modifications to ensure that there is no data loss when the same data is modified on multiple platforms at the same time, and to ensure the consistency of cross-platform data; this method involves some offline scenarios where the device may not be able to synchronize real-time data. The offline queue is used to ensure that offline data can be successfully synchronized after the network is restored, thereby improving adaptability to the network environment.

[0036] In this way, data interaction between the Hongmeng system and other mainstream systems can be achieved, ensuring the consistency of cross-platform data, reducing network bandwidth usage, and improving user experience and system performance.

[0037] In an embodiment of the present invention, the pseudo code of the incremental synchronization algorithm is provided as follows:

[0038] python def incremental_sync(last_sync_time):

[0039] changed_data=get_changed_data(last_sync_time)

[0040] for itemin changed_data:

[0041] if item.modified_time>last_sync_time:

[0042] sync_item(item)

[0043] update_last_sync_time()

[0044] Specifically, the steps for resolving conflicts in concurrent modifications include: maintaining a version vector for each data, the version vector being used to record the modification history of each device; identifying concurrent modifications by comparing version vectors; if a simple conflict is identified, attempting to automatically merge the simple conflict; if a complex conflict is identified, prompting the user to choose to keep the version.

[0045] It should be noted that, in the embodiment of the present invention, the version vector is a data structure that records the modification history of the data item on each device, and is usually set as an array, where each element of the array corresponds to the modification count of a device.

[0046] If the version vectors are different and have no inclusion relationship, it means that the data item has been modified concurrently. If the modifications of the two devices are simple conflicts, that is, they modify different parts of the data or data structures, the system can automatically merge these conflicts. If it is text data, the conflict can be resolved by merging the text; if it is structured data, the conflict can be resolved by merging the values ​​of the two fields.

[0047] It should be noted that when the system identifies a complex conflict, that is, two devices have modified the same data item and these modifications conflict with each other, such as modifying the same field or value, the system cannot automatically merge and must be handed over to the user to intervene to resolve the conflict. At this time, the system will display the conflicting data items and list the versions modified by each device. The user can choose which version to keep or merge the modifications manually.

[0048] Specifically, in an embodiment of the present invention, if an offline situation occurs, using an offline queue to assist in updating database data includes: saving local modified data in an offline queue; regularly obtaining local modified data in the offline queue from an API interface; using a timestamp-based incremental synchronization algorithm to update database data according to the local modified data obtained from the API; resolving conflicts for concurrent modifications; and after successful synchronization, removing the synchronized local modified data from the offline queue.

[0049] It should be noted that when the device is offline, the user can still modify the data, and the system will temporarily store the modified data in the offline queue until the device is back online. Since the background service regularly synchronizes the offline queue, data will be transferred at this time. In order to ensure the implementation of the timestamp-based incremental synchronization algorithm, whenever the device modifies local data, the system stores the modified data together with its timestamp in the offline queue. The data items are arranged in the order of modification to ensure that they are transmitted in the correct order during synchronization. After each synchronization is completed, the system will confirm which data has been successfully transmitted based on the synchronization results, and delete these data from the offline queue to ensure that only the data to be synchronized is stored in the queue.

[0050] Specifically, in the embodiment of the present invention, the unified data model is specifically JSON, XML or a binary protocol, and the unified data model is used to ensure the compatibility of data transmission and analysis between different platforms.

[0051] It should be noted that, in the embodiments of the present invention, the use of a unified data model simplifies the interface design of different platforms, so that the data exchange process is no longer limited by differences in platforms or operating systems. These formats can optimize parsing and transmission performance and reduce bandwidth usage.

[0052] In addition, an embodiment of the present invention also provides a cross-platform seamless data synchronization system for Hongmeng App development, the system including: an offline queue management module, the offline queue module is used to use the offline queue to assist in updating database data if an offline situation occurs; an incremental synchronization module, the incremental synchronization module is used to obtain data from the API interface; use a timestamp-based incremental synchronization algorithm to update the database data according to the data obtained from the API interface; a conflict resolution module, the conflict resolution module is used to resolve conflicts for concurrent modifications; a distributed data storage architecture module, the distributed data storage architecture module is used to store synchronized data; a central synchronization service module, the central synchronization service module is used to distribute data to the distributed data storage architecture module; a cross-platform adaptation layer module, the cross-platform adaptation layer module is used to achieve cross-platform compatibility.

[0053] Among them, the offline queue management module, the incremental synchronization module, the conflict resolution module, and the cross-platform adaptation layer module can provide technical effects consistent with the cross-platform seamless data synchronization method used for Hongmeng App development; the central synchronization service module is used to distribute data to the distributed data storage architecture module, and together with the distributed data storage architecture module constitute a special synchronization data storage and processing mechanism. Through the distributed data storage architecture module, the writing, reading and maintenance of synchronization data are distributedly processed, thereby improving the reading performance and reliability of the system.

[0054] Specifically, the distributed data storage architecture module includes a master database and several slave databases, the master database is responsible for data writing and consistency maintenance, and the slave databases are responsible for data reading and caching.

[0055] It should be noted that, in the embodiment of the present invention, the master database is the core component in the distributed architecture, which is responsible for all data writing operations and ensuring the consistency and persistence of the data. All data modification operations will first be written to the master database, and these operations will trigger the transaction processing mechanism to ensure the consistency and atomicity of the data; the slave database is responsible for processing data read requests and caching some commonly used data to reduce the burden on the master database and improve the read performance and scalability of the system. Moreover, since the slave database bears most of the read load, the response speed of the system can be significantly improved. When the master database fails, it can switch to the slave database to ensure the high availability of the system.

[0056] Specifically, the cross-platform adaptation layer module includes: a unified data model and API interface; adapters specific to the OS operating system platform, Android operating system platform and Hongmeng operating system platform, and the adapters are used to handle data type conversion and storage methods specific to the OS operating system platform, Android operating system platform and Hongmeng operating system platform.

[0057] Among them, the unified data model defines the standard format of data transmission on different platforms, so that different operating systems or hardware platforms can use the same method to represent and exchange data, providing a standardized framework for data transmission between different platforms; and the API interface defines how applications communicate with operating systems on different platforms, ensuring that applications on each platform can use the same interface to access services, operate data, etc. Developers can only focus on the unified API interface and data model without having to deal with differences between platforms, reducing development complexity. Specific adapters for the OS operating system platform, Android operating system platform, and Hongmeng operating system platform will automatically handle differences between platforms, simplifying cross-platform development.

[0058] Specifically, the conflict resolution module includes: a version vector mechanism, which is used to record the modification history of multiple devices; an automatic detection component, which is used to automatically identify concurrent modifications by comparing version vectors; an intelligent merge algorithm component, which is used to automatically merge when simple conflicts are identified; and a user-friendly interface, which is used to prompt the user to choose to retain the version when complex conflicts are identified.

[0059] Specifically, in the embodiment of the present invention, the offline queue management module uses persistent storage of the offline queue, and the locally modified data in the offline queue will not be lost after the device is restarted.

[0060] In addition, an embodiment of the present invention further provides an electronic device, including:

[0061] A computer program for executing the cross-platform seamless data synchronization method for Hongmeng App development as described above;

[0062] A memory, the memory being used to store the computer program;

[0063] A processor is used to execute the computer program.

[0064] To be more specific, with the popularization of smart devices and the increase in scenarios where multiple devices work together, users' demand for cross-platform data synchronization continues to grow, especially for the emerging Hongmeng OS ecosystem. Realizing seamless data interaction with other mainstream operating systems such as Android and iOS is particularly critical for the development of APPs under the Hongmeng OS ecosystem.

[0065] At present, the existing data synchronization technology mainly has the following problems: data consistency is difficult to ensure, network bandwidth consumption during the synchronization process is large, synchronization reliability is low in an unstable network environment, and cross-platform compatibility is poor. Based on this, the technical solution involved in the embodiment of the present invention makes the following comprehensive improvements.

[0066] The technical solution involved in the embodiment of the present invention reduces the compatibility difficulty of data between different platforms by designing a standardized data model and constructing a platform-independent API interface. This standardized processing enables different platforms to seamlessly interact with data, improving the consistency and accuracy of data. The implementation of specific adapters enables the Hongmeng system to interoperate and synchronize data with other mainstream platforms under different storage models and data formats. This greatly expands the application scenarios and compatibility of the Hongmeng App, and the incremental synchronization algorithm only synchronizes the changed data, reducing the redundant transmission of data, thereby optimizing the use of network bandwidth. At the same time, this algorithm also improves the synchronization speed, reduces the user's waiting time, and can achieve conflict resolution for concurrent modifications, ensuring that there will be no data loss or overwriting when the same data is modified on multiple platforms at the same time, thus ensuring the consistency and integrity of cross-platform data. In addition, the use of the offline queue management module enables the device to store the data to be synchronized even when it is offline, and synchronize after the network is restored, which improves the adaptability of the system to the network environment and ensures the real-time and integrity of the data. The distributed data storage architecture module and the central synchronization service module together constitute a special synchronization data storage and processing mechanism, which improves the system by distributing the writing, reading and maintenance of the synchronization data. Reading performance and reliability. This architecture enables the system to process a large number of data synchronization requests more efficiently, improving the overall performance of the system. In summary, the technical solutions involved in the embodiments of the present invention can realize data interaction between the Hongmeng system and other mainstream systems, ensure cross-platform data consistency, reduce network bandwidth occupancy, and improve user experience and system performance. Compared with the existing technology, it has the following technical advantages: millisecond-level data synchronization, greatly improving user experience; ensuring data consistency across devices and platforms; significantly reducing network bandwidth occupancy and data transmission volume; improving the synchronization success rate in unstable network environments; and realizing seamless data synchronization between Hongmeng OS, Android and iOS platforms.
