Abstract

The invention relates to the technical field of computer application, in particular to a cloud database system used for distributed heterogeneous data resource integration. The cloud database system is composed of a metadata service node, a service node, a front-end computer node and a production computer node, the metadata service node provides a system service to realize overall management of the whole cloud database system, the service node mainly provides a data service, various heterogeneously-distributed databases or file systems on the front-end computer node serve as data sources of the cloud database system, and the data sources are accessed to the inside of the cloud database system through an access mechanism provided by the cloud database system; a production system writes data into a database system on the production computer node in real time, and then the data are periodically copied on a front-end computer by a data synchronization module of the cloud database system. The cloud database system solves the problem of integration of distributed heterogeneous information resources and can be applied in a distributed-type heterogeneous database.
