Embodiment Construction

[0045] The method of the present invention is described in detail below with reference to the accompanying drawings.

[0046]The technical problem to be solved by the present invention is to provide a simple and quick method to access and process a large number of business table data, reduce the logic code during business processing, improve work efficiency, and conveniently extract table data through this invention and exchange operations. At the same time, the business rules extracted from the business are used to establish data element catalogs and value domain catalogs to standardize business information.

[0047] Technical solutions:

[0048] Technical scheme of the present invention is made up of following several parts:

[0049] (1) Element system model design;

[0050] (2) Definition of business table information;

[0051] (3) Data element and value range definition;

[0052] (4) Database model table information data extraction;

[0053] (5) Metasystem-based da...

Abstract

The invention provides a meta-system design method based on a data model, relates to a meta-system design based on a data structure, and aims to simplify the processing logic of a large number of service table data in a service system, extract table information and field information by arranging the table information and the field information of a service table, and store the table information and the field information into a meta-system definition table. Meanwhile, a data element and a value domain code are extracted based on the service table and service field information, a data element catalogue and a value domain code catalogue are maintained in a meta-system, a reference relationship between the field information and the data element is established, semantic mapping is realized to ensure that each service field has a uniform format specification, and uniform accessing and extension processing are carried out on the service table data by the meta-system through these defined data.

Description

technical field [0001] The invention relates to a computer application technology, specifically a meta-system design method based on a data model. The invention is aimed at a software system with a large number of business tables, and is an extended application of a database logic model. Through the extraction and refinement of business table information data, data element catalogs and value field codes are established, and the mapping relationship is used to maintain the relationship between table fields / data elements, data elements / value fields, and standardize business data. At the same time, the business table information, field information, data element directory, and value field code directory are stored in the database table as the basis of the element system. During use, data processing is performed by reading meta-system data, which simplifies business logic and provides extended services. Background technique [0002] There are a large number of business forms in ...
