Data reading/writing method and system, and database system

Abstract

The invention discloses a data reading / writing method and system. The method comprises the steps of writing to-be-stored data in a master database when a data writing request is received; writing data stored in the master database into corresponding slave databases according to a predetermined rule; and determining slave database identifiers stored in to-be-read data when a data reading request is received, and reading the data from the corresponding slave databases according to the slave database identifiers. According to the method and the system provided by embodiments, the data is all written in the master database, the master database writes the data in different slave databases, and the slave databases only make a response to the data reading request, so that data reading and writing are separated and data access performance is improved; and a database system is isolated from a business system through a unified data platform, so that underlying data maintenance and expansion do not influence normal operation of the business system. The invention furthermore discloses the database system, which also can achieve the abovementioned technical effects.

Description

technical field [0001] The invention relates to the technical field of data reading and writing, and more specifically, relates to a data reading and writing method, system and database system. Background technique [0002] At present, when dealing with data reading and writing, generally a single database server can meet the demand, but with the growth of data, a single database server may not be able to support the huge access pressure, and a single database server is executing multiple databases at the same time. When reading and writing operations, since all read and write operations are performed on the same database, when there is more data, it will have a great impact on the read and write performance of the database. [0003] Therefore, how to read and write data from the database and enhance the read and write performance of the database is a problem to be solved by those skilled in the art. Contents of the invention [0004] The purpose of the present invention ...

[0002] At present, when dealing with data reading and writing, generally a single database server can meet the demand, but with the growth of data, a single database server may not be able to support the huge access pressure, and a single database server is executing multiple databases at the same time. When reading and writing operations, since both read and write operations are performed on the same database, when there is more data, the read and write performance of the database will be greatly affected
