Abstract

The invention discloses a data access method and equipment. The method comprises following steps: obtaining a database access request, wherein the database access request comprises sqlid, fragmented fields and data request parameters; determining virtual library table identification according to the fragmented fields and the sqlid, wherein the virtual library table identification is a logic identification of an entity library table in a system; obtaining an entity library table A required accessing according to the mapping relationship between the virtual library table identification and the entity library table; after combining statement parameters in the data request parameters with the sql statement corresponding to the sqlid, accessing the entity library table A to obtain an access result. Therefore, the method and equipment effectively solve the technical problem of high maintenance cost of fragment routing rules in the prior art, and have the beneficial effects of reducing the modification of fragment routing rules and the operation cost of fragment routing rules.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a data access method and device. Background technique [0002] With the development of Internet business, the business volume of trading system has increased exponentially. At the same time, Internet businesses often carry out promotional activities, which will lead to a surge in transaction volume and a transaction peak within a certain period of time. At present, transaction systems generally rely on databases as a tool for data persistence. Once a transaction peak occurs, database operations will become a bottleneck. [0003] Therefore, the distributed database solution is widely used by Internet companies to horizontally split the database table into multiple tables in multiple libraries to reduce the processing load of each fragmented table and improve the access efficiency of the database as a whole. It is necessary to formulate shard routing rules to realize data acc...
