METHOD FOR ACHIEVING AUTOMATIC SYNCHRONIZATION OF MULTISOURCE HETEROGENEOUS DATA RESOURCES

摘要

The present invention relates to a method for achieving automatic synchronization of multisource heterogeneous data resources. The present invention relates to a metadata serving node, a serving node and a production node. The metadata serving node is responsible for storing a data dictionary in a distributed heterogeneous database system; the serving node is responsible for parsing a user request in the heterogeneous database system, and regularly conducts synchronization with a database on the production node; and the production node is responsible for requesting query, update, etc. in a corresponding production application system, wherein the serving node is composed of a configuration recognizer, a log parser and a data synchronizer, wherein the configuration recognizer is used for analyzing the configuration of a source database on the production node and selecting an available synchronization method, the log parser is used for parsing logs of different database systems, and is a preparatory working part in an increment synchronization manner, and the data synchronizer conducts data synchronization according to the synchronization method of the configuration recognizer. The present invention achieves the automatic synchronization of multisource heterogeneous data resources, and can be used in the processing of data resources.
