Abstract

The invention provides a data synchronization method and system. The method comprises the steps that a first database system acquires an SQL statement sent by an application program to a second database system; the first database system executes database operation corresponding to the SQL statement; and according to state records of database operation executed by the first database system and thesecond database system, the first database system performs database operation on a first database thereof, so that the first database is consistent with a second database of the second database system. Through the data synchronization method and system, the problem that in the prior art, a database synchronization technology has low efficiency in the remote synchronization field or does not support synchronization of heterogeneous databases is solved, database synchronization efficiency is improved, database synchronization expenditure is lowered, and support of the heterogeneous databases isrealized.

Description

technical field [0001] The invention relates to the field of database synchronization, in particular to a data synchronization method and system. Background technique [0002] In the information age, data is growing in a blowout manner. For this reason, many Internet and financial companies have established multiple cross-regional data centers. And if most data centers are only used as disaster recovery, it is a waste. Therefore, many enterprises are exploring the construction of data centers in the remote multi-active mode, that is, remote data centers not only have disaster recovery capabilities, but also have the function of business distribution to undertake production tasks. The key to realizing multi-active in different places lies in the efficiency of database synchronization. [0003] The database synchronization method in the related art is based on the incremental log of the database. For example, the Oracle Streams cluster series uses advanced queue technology ...
