Abstract

The invention discloses a data synchronism method. The method includes the steps that when it is detected that data increment exists in an original database, the data increment is synchronized to a middle open source database, and a binary system log of the middle open source database is updated; partitioning key value and data increment change information are obtained according to the binary system log; the fragmentation number of a target database is determined according to the partitioning key value, the data increment of the middle open source database is transmitted to the target data base corresponding to the fragmentation number, and synchronism operation is executed in the target database according to the change information. By means of the method, data synchronism can be conductedwithout drop line, and the system down maintenance cost is reduced greatly. The invention further discloses a data synchronism having the advantages above.

Description

technical field [0001] The invention relates to the field of data storage, in particular to a data synchronization method and system. Background technique [0002] With the rapid development of science and technology, the integration of Internet technology with daily life and business activities is becoming increasingly close. The 7*24 service system is growing rapidly like mushrooms after rain, so the need and requirements for data storage are getting higher and higher, especially in the fields of finance, government affairs, e-commerce, etc., the data access service provided by the database has become an important part of its business. ring. [0003] As far as the financial system is concerned, the daily transaction volume generally reaches millions, and the data increment can reach megabytes or even billions of bytes. The traditional single data cannot meet the actual needs of such systems. In the prior art, when the original database is synchronizing data, the data fra...
