Problems solved by technology

In each upgrade, the design and development of new database tables is required, which brings a lot of workload and upgrade costs to daily development and upgrades, and cannot respond quickly to changes in requirements
Since the database table and field structure are the bottom-level structure of the application system, it is also the most important structure. If the database table and field structure change frequently, the upper-level system needs to be updated and upgraded accordingly, which will reduce development efficiency and also affect System correctness and stability

Abstract

The invention provides a relation-type database expansion method and a relation-type database expansion system. A database table comprises expansion fields, wherein default format texts serialized by class files are saved in the expansion fields; content of the default format texts is read from the expansion fields, and the content of the default format texts is de-serialized into matched class files; the operation on the class files are responded and the operated class files are serialized into the default format texts and then saved in the expansion fields. By means of the method and system, the design development work and change work of database table for every update can be reduced.

Description

technical field [0001] The invention relates to the field of database design, in particular to a relational database extension method and a relational database extension system. Background technique [0002] RDB (Rational DataBase) is a database built based on various entities in the real world and various connections between entities. Relational databases store data in the form of database tables, and most database tables use a field (column) to store an attribute, please refer to figure 1 , if an entity has 10 attributes, it is necessary to design a database table with 10 fields (columns) to store each attribute of the entity. [0003] With the continuous iterative update of business system requirements and functions, the attributes of entities will also increase or decrease accordingly. Among them, there is a class of entities whose basic attributes are consistent, but each entity has its own unique extended attributes. If each existing field (column) is used to store a...
