Embodiment Construction

[0073] For the sake of illustration, take the scholarship evaluation of students by the Academic Affairs Office of a university as an example, assuming that there are three business systems in the university: the student educational administration system, the student financial system, and the student scientific research system, and the student information required for the scholarship evaluation work involves these three business systems ;The educational administration system has a student achievement data set, and the basic tables it includes are shown in Table 1, Table 2, Table 3, and Table 4; the financial system has a student financial data set, and the basic tables it includes are Table 5, Table 6, and Table 4. 7. The scientific research system has a student scientific research data set, and the basic tables it includes are shown in Table 8, Table 9, and Table 10; the attributes Sno, SF_no, and SR_no are semantically equivalent and interdependent in the three business system...

Abstract

The invention discloses a data service dependency graph-based automatic generation method for a data combination view for a university. The method comprises the steps of firstly packaging a data set of various departments of the university into atomic data service, packaging and registering the atomic data service on the basis of an REST technology and carrying out unified management; secondly, building a data service dependency graph of various departments of the university according to an internal dependency relationship in the atomic data service; thirdly, automatically combining the atomic data service to generate composite data service according to data requirements of a user on the basis of the service dependency graph; and finally executing the composite data service to generate the data combination view, and returning the data combination view to the user in a form of a table. An effective automatic generation method for the data combination view is provided for data integration of various departments of the university, so that the automatic degree is improved.

Description

technical field [0001] The patent of the invention relates to the fields of university data integration, data service, and view generation. In particular, it provides a method for automatically generating university data combination views based on data service dependency graphs. Background technique [0002] With the in-depth development of digital campus construction, all departments of universities have established business information systems, such as portal system, educational information system, teaching information system, personnel information system, scientific research information system, etc. , financial and personnel data. Because these information systems use different databases and development technologies, data are stored across platforms and are heterogeneous, forming "data islands" that make it difficult to integrate and share data scattered in various departments of universities. Therefore, how to integrate cross-departmental heterogeneous data and meet use...
