Problems solved by technology

It can be seen that when data synchronization fails or the local database fails, the caller needs manual intervention and cannot automatically switch to the remote database to query the correct data, which reduces the efficiency of the caller's access to data

Abstract

The embodiment of the invention discloses a data access method and device, wherein the method comprises the following steps that a data access request is received; an effective sign of duplicate data in a local database is read, wherein the effective sign comprises a first sign value or a second sign value; whether the effective sign is the first sign value or not is judged; if so, a local database is accessed according to the data access request; if not, a remote end database is accessed according to the data access request. When the method and the device provided by the embodiment of the invention are implemented, the efficiency for calling the access data can be improved, and in addition, the automatic conversion among multiple data sources can be realized.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to a data access method and device. Background technique [0002] In a complex enterprise-level application environment, a large number of callers often need to perform high-concurrency access to remote databases that store public data. In order to reduce the pressure on the remote database, it is usually necessary to copy the master data in the remote database to the local databases of multiple callers. The caller can obtain the copy data by accessing the local database. The common practice of enterprises is to purchase a dedicated Data replication products to achieve data replication. [0003] In an enterprise-level environment where there are many callers and the master data and replica data exist at the same time, when the data synchronization update fails or the local database where the replica data is stored fails to be repaired, in order to ensure that the acce...
