Model and modeling method of multi-dimensional data integration of heterogeneous databases of electric power information system

The invention relates to a model and modeling method of the multi-dimensional data integration of heterogeneous databases of an electric power information system. The modeling method comprises the following steps of: (a) establishing a basic container hierarchical structure, predefining a template for each container, i.e. standardizing the problem of loading objects during the actualization of the containers according to the type of the containers, classifying the abstract containers into a plurality of types, and modeling by utilizing the container templates and the hierarchical relational structure thereof; (b) establishing a uniform and standardized common naming method for managing heterogeneous object models of the electric power information system so that a private object of each data source can be reduced to a same common object; (c) loading the common object to private object mapping relationship, establishing common object information, private object information of the heterogeneous databases and the mapping relationship of the common object information and the private object information of the heterogeneous databases through XML (Extensive Makeup Language) description files which are derived by the data sources and contain common names, and loading the objects and the mapping relationship thereof into a hierarchical container model established in the step (a). The invention reduces the complexity and the cost of the data integration without secondary development and maintenance.
