Abstract

The invention discloses a universal database conversion device, which comprises a database creation module, an analysis module and a reverse module. The database creation module receives an edited database design file, calls the analysis module to analyze design statements in the database design file line by line and generates corresponding SQL statements, and executes the SQL statements to create a database object; the reverse module reversely generates the database design file from a target database. The device can be compatible with various database types, can be repeatedly executed when the database is created, can automatically judge whether a database object exists or not, and does not create existing database objects any more, so that execution errors are avoided. An instance database can be converted into a design document, and the original design is compared with a reversely generated document, so that the data standard implementation of each industry is further checked. Therefore, the efficiency of creating the database is improved, and the maintenance cost is also reduced.

Description

technical field [0001] The application belongs to the technical field of databases, and in particular relates to a general-purpose database conversion device. Background technique [0002] Some application software based on database operation may need to support multiple different database types. Common database types include ORACLE, DB2, MYSQL, SQLSERVER, etc. The development team usually completes the database design first, and creates a set of data structure creation statements for each database type. These codes have the same logic, but the syntax of different types of databases is different, so the creation of data structure statements needs to be maintained. . In the operation and maintenance process after going online, it is often necessary to expand or modify the database table structure. These codes are prone to inconsistencies, resulting in a large workload for software testing. Because the action of modifying the database structure is non-repeatable and requires...
