Abstract

The invention discloses a method for managing metadata of a virtual data warehouse of an electric power information system group. The method comprises the following steps of: a) managing an object data service of a public electric power information system, and managing the public data service attribute provided by a public object for query; b) managing the mapping relationship between a public data service and a private multi-dimension data service of each heterogeneous database, wherein the established mapping relationship of the public data service and the private multi-dimension data service of each heterogeneous database is finished through the incidence relation from the public data service attribute to each heterogeneous source table column; and c) managing a public data service interface and a maintenance interface, and managing a set of open standard interface (API) function library for providing external data services. The public data service interface comprises a unified retrieve definition interface and a unified data query service interface. By using the method, private data services provided by each power information system are integrated, and the public data services provided for a third party are summarized. The method can be conveniently applied to integration work of the electric power information group.
