Zusammenfassung:The invention provides an XML (extensive markup language) native database-based hybrid access method for a power network data model. The hybrid access method comprises the following steps of determining the power network data model, and dividing the power network data model into a basic data type and a complex data type; storing the basic data type by basic data type of a relational database, and storing the complex data type by XML native data type; performing multi-stage partition on the complex data type, and repeating the steps; extracting the power network data model according to a unique number. According to the XML database-based hybrid access method for the power network data model, provided by the invention, based on the object-oriented strategy, by comprehensively utilizing the advantages of the relational database and an XML format, rapid storage, query and conversion of power network data are realized.
