Abstract

The invention discloses a synchronizing system for database conversion and a method for the same. The system comprises a database converter and a data network bridge, wherein the database converter can convert tables in a source database to a target database. The data network bridge comprises an instruction analysis unit, a storage unit and a synchronous control unit, wherein the instruction analysis unit receives a database query instruction and analyzes the enquired table related to the database query instruction; the storage unit temporarily stores the database query instruction; and the synchronous control unit decides a query mechanism and receives a conversion state of the inquired table returned by the database converter, and the synchronous control unit executes the database query instruction to the source database or the target database of both the two databases according to the query mechanism and the conversion state.

Description

technical field [0001] The invention relates to a synchronous system and method thereof, in particular to a synchronous system and method thereof which support query when the database is converted. Background technique [0002] Database synchronization is used to avoid different values ​​of the same data in different tables or different databases. For the synchronization of different databases, most of the current synchronization methods use a timing synchronization mechanism, that is, in a specific Start the data conversion between the source database and the destination database at the point in time to achieve the purpose of synchronization. However, while the database is being converted, the user's access to the database is limited, such as the inability to query the database or the performance of the query is low. Preventing such problems is essential for a real-time system or a database that emphasizes high performance. It is extremely important in the management syste...
