Referring to fig. 1-2, the present invention provides a technical solution: a data governance system based on a unified data resource pool, comprising:
the data access module is used for realizing complete access of data resources of the data source;
the data processing module is used for carrying out standardized processing of extraction, cleaning and conversion on data resources;
the data management and control module is used for carrying out full life cycle management of data standard management, metadata management and resource catalog management on data resources;
the data resource pool module is used for carrying out classified management on the data resources;
the data service module is used for performing service encapsulation on the data resources and providing data resource services;
and the data sharing and exchanging module is used for performing cross-service, cross-application and cross-department information sharing on the data resources.
The data source comprises external associated department data, internal business department and transcription department data of the emergency management bureau, social internet public data and perception data. The data of the external association department and the data of the internal business department and the transcription department of the emergency management bureau can be accessed into the data buffer area through the business system by adopting the access preposition, thereby realizing the data access.
The access mode of the data source comprises a database access mode, a file access mode, an interface calling mode and a data exchange mode. For the existing established system access, the system which has been applied and integrated adopts a one-time full access mode to carry out data migration, and continues to use a system full data extraction and increment synchronization mode to carry out access; and planning a newly built system to carry out data access and exchange according to the real-time requirement.
