Embodiment Construction

[0036] The nodes in the system of the present invention are divided into four types, including: metadata service nodes, service nodes, front-end machine nodes, and production machine nodes.

[0037] metadata service node

[0038] Logically, there is only one metadata service node in the system, and there can be multiple metadata service nodes in physical deployment, which serve as mutual backups to improve system availability. The metadata service node provides system services to realize the overall management of the entire cloud database system, including tenant management services, system monitoring services, data directory services, system log services, and system management interfaces.

[0039] Tenant management services mainly provide management services for virtual database administrators in the cloud database system, including registration, approval, and login of virtual database administrators. This embodies the idea of ​​multi-tenancy of the cloud database. Users can...

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.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to a cloud database system for integrating distributed heterogeneous data resources. Background technique [0002] Public information resources include information resources collected by government departments in accordance with the law, information resources generated by government departments in the process of performing their functions, information resources invested and constructed by government departments, and information resources authorized and managed by government departments in accordance with the law. Judging from these content characteristics of public information resources, the main body of collecting, processing, storing, managing, and using public information resources is government departments at all levels, such as industry and commerce, taxation, planning, land, real estate, transportation, etc. Therefore, physically, public information resources are...
