摘要

A kind of method, in order to generate can be obtained from data source desired data integrated view generate a database schema disperse and be stored in the different formats of different positions, provide a kind of data integrated system. This method comprises: it is regular, it is used to analyze the content of structure and the database described in a specification normative language, generates semantically framework corresponding with database, determine the data items for needing to generate an integrated view. In addition, expressing an integrated view to generate a global schema, the part of XQuery grammers will be introduced for local mode, express a single database, and the definition that canonical representation is used to express a Data View is included. Correspondingly, the integrated view that a kind of data integrated system can produce the various heterogeneous databases for being dispersed in a network puts up inquiry by using a specification normative language in real time.
