Research And Implementation Of The XML-based Data Exchange Middleware

This paper researches on data exchange. Its purpose is to realize the interconnection and information sharing among every "detached island of information". In data exchange process, two key points are data isomerism and dynamic configuration. The adoption of XML and Plugin technology has offered a kind of new scheme of settlement for data exchange.This paper has carried on the induction and the summary according to the data isomerism. Then it expresses the structure information and value information separately with two XML files. It realizes data exchange through the analysis of data structure files and rule files user defined. After that the paper has designed and implemented a XML-based Data Exchange Middleware (XDEM). XDEM separates treatment method from data processing procedure. Users can customize different treatment for differentoccasions so as to strengthen adaptability and expansion.In the concluding part, the paper summarizes the design and realization of XDEMand suggested the future improvement on it.
