Description

Technical Field

[0001] The present application relates to the technical field of data asset management, and more specifically to a unified data-driven zero-code construction system and method for information services for universities. Background Art

[0002] A large amount of data resources are stored in the information systems of universities. In order to realize the comprehensive utilization of this data resource, more and more universities have purchased big data analysis and management systems to cope with the scenario requirements of real-time processing of massive concurrent data. However, for specific application processes that require distributed stream computing, currently only a single stream processing platform can be selected, programming operations are performed first, and then execution is performed. The operation process requires high technical personnel capabilities and the code reusability is poor. The existing technology needs to arrange special maintenance and update personnel to regularly sort out the business needs of university information systems and then rewrite and release new algorithm modules to adapt to the development of university business needs.

[0003] However, due to the limitations of data silos in existing university databases and the lack of existing data links, in actual application, the standardized analysis system is often unable to retrieve or identify corresponding data resources and cannot realize its due functions. The contents displayed by the reporting system, query system and business topics are independent of each other and cannot meet the diversified needs of business departments.

[0004] In addition, the existing university information service system has a long development cycle and slow response to new business modules. It needs to go through several stages of demand confirmation-design-coding-testing-acceptance before it can be officially put into operation. The development cycle is long and the cost is high. The business needs may change just after the system is developed, so it is difficult to meet the flexible and changing needs of the business department. Summary of the invention

It should also be understood that terms such as those defined in a general dictionary should be understood to have a meaning consistent with the meaning in the context of the prior art, and will not be interpreted in an idealized or overly formal sense unless defined as such herein.

[0023] The meaning of "connection" as described in the present application can be a direct connection between components or an indirect connection between components through other components.

[0024] Figure 1 A unified data-driven zero-code construction system for colleges and universities according to the present application includes:

[0025] A data storage entity for storing unified metadata. Each unified metadata uniquely corresponds to a data identifier, and respectively records each service item corresponding to the unified metadata, as well as the description value, data type, format, whether it can be null, and attribute information of each service item according to a unified standard, and records the process storage link of the unified metadata.

[0026] A process storage unit corresponding to the process storage link of each unified metadata, respectively stores all process data in the entire life cycle of the unified metadata, and marks the storage time of each process data therein.

[0027] A data layering unit that, according to service call conditions, assigns corresponding levels to each unified metadata in a data storage entity, retrieves the unified metadata belonging to the same level, and stores it in a level storage unit corresponding to that level;

[0028] A form construction module that receives terminal service requirements through a general interface and retrieves data from each level storage unit according to the terminal service requirements to generate a form;

[0029] A general interface that is respectively connected to each information service interaction terminal, used to provide a form interface for the information service interaction terminal to obtain data, and also used to receive operation instructions feedback by the information service interaction terminal, and parse each operation instruction into terminal service requirements and issue them to the corresponding form construction module;

[0030] The information service interaction terminal, in response to the user's operation on the visual interface, matches an independent port for each visual window on the information service interaction terminal interface through a process engine, receives the user's operations on each visual window through each port, as well as the user's settings of the logical relationship and operation steps between this window and other visual windows to generate corresponding operation instructions, and feeds back the operation instructions to the general interface. By implementing various operation instructions in the application, the object of the operation instruction is generally set to the data or form operated by the user in the visual window, or when setting the visual window attributes and the logical relationship between windows, the object of the operation instruction is set to the visual window itself; the instruction type is the operation type selected by the user in the visual window, including operations such as modifying, calculating, and statistical operations on specific data, as well as merging and updating forms, and also including setting the logical relationship and call sequence between visual windows.

[0031] The process engine therein includes multiple processing unit operators adapters for a streaming analysis platform, used to publish the process to one or more streaming processing platforms through steps such as process parsing, execution platform judgment, unit processor adaptation, application compilation, application packaging, and application release. The streaming analysis platform and the streaming processing platform include STORM and / or SPARK and / or FLINK.

[0032] Thus, this system can store each faculty member, each student, each course, and each asset in the existing university systems as a unified metadata item according to a unified standard, and assign a unique data identifier to each unified metadata item according to a preset coding rule. It records the business item corresponding to the unified metadata, as well as the description value, data type, format, nullable property, and attribute information of each business item according to the unified standard, and records the process storage link of the unified metadata. The unified metadata is stored in the data storage entity, and according to the process storage link, the data belonging to the same faculty member, the same student, the same course, and the same asset in the existing university systems are respectively collected into the process storage unit matching the unified metadata item, and in the process storage unit, the description value, data type, format, nullable property, and attribute information of each business item are set according to the business item represented by the data, and the storage time of each process data is marked according to the update time of each business item description value, so as to realize the storage and update of all process data in the complete life cycle of the unified metadata;

[0033] Then, according to the business call situation, the data layering unit assigns levels to each unified metadata in the data storage entity, stores the unified metadata with a higher call frequency in the first-level storage unit, and collects the unified metadata with a lower call frequency according to the call frequency, data type, or data attribute. The data with similar call frequencies, the same data type, or similar data attributes are stored in the storage units of the same level corresponding to this level respectively.

[0034] When each information service interaction terminal receives the operation of the user on the visualization window in its interface, it performs the following steps:

[0035] In response to the operation of the user on the visualization interface, generate corresponding operation instructions through the process engine and feedback them to the general interface,

[0036] Parse each operation instruction into terminal service requirements through the general interface and issue them to the corresponding form construction module;

[0037] The form construction module retrieves the data in each level of storage unit according to the terminal service requirements to generate a form, so as to provide a form interface to the information service interaction terminal through the general interface for the information service interaction terminal to obtain and receive the operation of the user on the corresponding data in the visualization interface.

[0038] Thus, the user can retrieve, calculate, or update forms and data by operating on the visual interface. For example, when the user modifies the data in the visual interface, the information service interaction terminal correspondingly feeds back the operation of updating and adjusting the data in the form in the visual interface to the general interface. At this time, the general interface first verifies the permissions of the information service interaction terminal. When the information service interaction terminal meets the permission requirements corresponding to the relevant form, it parses the operation instruction of adding and adjusting the data in the form into terminal service requirements and issues them to the corresponding form construction module, so as to trigger the update or adjustment operation of the data in the corresponding hierarchical storage unit through the form construction module; when the information service interaction terminal does not have the permission, it triggers the visual interface to give a permission prompt. Thus, when the data layering unit detects an update or adjustment operation on the data in the corresponding hierarchical storage unit, it first queries the process storage link of the corresponding unified metadata in the data storage entity according to the data identifier, adjusts the current value of the unified metadata to the process data pointed to by the process storage link, marks the storage time of the process data, and updates the new data corresponding to the update or adjustment operation to the unified metadata.

[0039] When the user adds new data through the visual interface, the information service interaction terminal correspondingly feeds back the operation of adding data in the form in the visual interface to the general interface. At this time, the general interface first verifies the permissions of the information service interaction terminal. When the information service interaction terminal meets the permission requirements corresponding to the relevant form, it parses the operation instruction of adding data in the form into terminal service requirements and issues them to the corresponding form construction module, so as to trigger the update or adjustment operation of the data in the corresponding hierarchical storage unit through the form construction module; when the information service interaction terminal does not have the permission, it triggers the visual interface to give a permission prompt. Thus, when the data layering unit detects an update to the data in the corresponding hierarchical storage unit, if it fails to query the process storage link of the corresponding unified metadata in the data storage entity, it adjusts the currently updated data to the unified metadata corresponding to a new data identifier, and correspondingly marks the storage time of the data in the process data of the unified metadata, and sets the permission requirements of the unified metadata to be consistent with the permissions of the information service interaction terminal that triggers the data update operation, so as to realize the update of the unified metadata in the data storage entity.

[0040] When a user hopes to add a functional module in the visualization window to implement new data processing functions, the operations of the user on the visualization window and the settings of the logical relationships and operation steps between the visualization windows can be received through the ports corresponding to the visualization windows; then, through the program mapping unit, according to the operations and settings received by each port, a calculation model is constructed accordingly, each step of the operations to be performed on the window, form or data is recorded, and a form retrieval list is configured for the calculation model according to the form content retrieved by each visualization window; and then by the encapsulation unit, an executable program applied to different types of information service interaction terminals is compiled and generated based on the calculation model constructed by the program mapping unit and its corresponding form retrieval list. Thus, when the user needs to retrieve and use the custom data processing function, the corresponding executable program is selected through the visualization window, and then the program execution unit is triggered to respond to the retrieval operation of the calculation model by the user in the visualization window, retrieve the executable program matching the terminal according to the type of the information service interaction terminal, map the settings of the forms and parameters required by the user for the calculation model in the visualization window to the executable program, and execute the corresponding operation instructions according to the executable program and trigger the visualization window to return the execution result after the program execution is completed.

[0041] In a more preferred implementation manner, the present application can further set a data layering unit to label the unified metadata of each hierarchical storage unit belonging to the same form according to the retrieval operations of the form construction module on the data in each hierarchical storage unit. Thus, when the form construction module retrieves the data in each hierarchical storage unit according to the terminal service requirements and generates a form, it can first retrieve the unified metadata with the same label to the same form according to the label of the retrieved data, and then set the label of the data that has not been actually retrieved to a null value according to the terminal service requirements, and remove the data with a null label from the form to improve the data retrieval efficiency.

[0042] For the data that appears in different forms such as ordinary tables, fact tables (daily / monthly statistical tables, tables divided by day / month / year, daily summary tables), dimension tables, temporary tables, external tables, and interface tables at the same time, the present application can further set the form construction module to, during the process of generating a form, only retrieve the unified metadata with the same label to the same form according to the label that appears the most times in the retrieved data in the existing form, so as to avoid repeatedly retrieving irrelevant data and affecting the system operation efficiency.

[0043] The above-mentioned label can also facilitate the statistics and analysis of the data in the same data processing process. During statistics and analysis, by directly retrieving the corresponding data through the label, the required results can be obtained according to the variable values or any attributes and update information of the data.

[0044] In summary, the present application independently stores all updates of the unified metadata during its complete life cycle through the process storage unit, which can realize accurate tracking of each unified metadata. The data stratification unit stores the frequently retrieved data in the hierarchical storage units such as ARM and registers according to the frequency of data retrieval, and stores the data with lower call frequency in the storage units of other levels, which can ensure the rapid and accurate retrieval of data while further ensuring the accuracy of retrieval of unpopular data without worrying about data loss and other problems. The present application receives the operation instructions of the information service interaction terminal under different operating environments through a universal interface, can realize form data interaction through the form interface, and realize new data processing functions through the process engine according to the calculation model set by the user. The system of the present application separates the unified metadata from its historical modification records and indicators such as permissions and attributes, can simplify the calling process of the unified metadata, and only realizes the update of the current numerical value of the unified metadata by updating the process data, thereby avoiding external data attacks and realizing the isolation and protection of university data resources.

[0045] This application can abstract the business functions in the university system in a low-code manner through a visualization window, and implement the corresponding functional units through all independent windowed functional components. And it can realize self-defined functions according to the user's operation on the visualization window. The calculation model built in this way can flexibly adapt to user needs, save secondary development costs, and achieve compatibility with multiple types of information service terminals through a universal interface.

[0046] In addition, the present invention is based on a rich modular architecture, and can realize rich data source management functions through process storage units, form construction units, process engines and general interfaces. The present application can realize the rapid design of visual data models through a graphical visualization interface based on WEB, by dragging, pulling, and dragging the visualization interface, and setting parameters or interface attributes and logical relationships therein. The present application can also realize the annotation and interpretation of each unified metadata by adding marking marks, and can improve the efficiency of the form construction module in generating and providing form data by classifying and searching the marking marks.

[0047] The above is only an implementation method of the present application, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present application. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application.
