Research and Implementation on Multi-Database System Based on XML

Abstract

This paper introduces advantages of XML as a data exchange format, and proposes a multi-database system architecture based on XML, a data exchange platform model. We takes full advantage of is the features of XML, including good extensibility and interactivity, to implement the XML-based integration program of heterogeneous databases, making all kinds of data described in a unified XML format. And we describe the actual workflow of the system in this model and theoretically analyze the implementation details of its core modules. Finally, the workflow and the multi-database work mode for users to access databases in the system model based on XML are presented.
