A method for automatically synchronizing multi-source heterogeneous data resources utilizes a metadata service node, a service node and a production node, wherein the metadata service node stores a data dictionary of a distributed heterogeneous database system, the service node parses user requests of the distributed heterogeneous database system, for regularly synchronizing data with the production node; and the production node provides requests such as querying and updating of a relevant production application system; wherein the service node includes a configuration analyzer, a log parser and a synchronous update device; the configuration analyzer analyzes source database configurations on the production node, and selects an applicable synchronization method; the log parser parses logs of different database systems, which is a preparatory component of incremental synchronization; the synchronous update device recognizes the synchronization method according to the configuration analyzer for data synchronization. The method realizes automatic synchronization of the distributed heterogeneous database system, and is applicable to data resource treatment. |
