Researching A Data Management System Based On XML

It is important for a Data Management System (DMS) to share and exchange data in different applications. As a result, the efficience and maintenance of software can be improved. In this paper, a Data Management System based on XML technology is studied and it can resolve the problem in data lay.In this DMS, the data of applications can be described in XML document. Because of the capability of XML, the currency and expansibility of applications can be improved.In this paper, it is researched that how to implement the format conversion between C++ objects instance and XML documents in VC++ flat. Two operations (pack and unpack) are analysed in detail. It is researched maily that how to implement the currency of them.This paper discusses the methods that how to store the XML document. One that based on path analysis (XRel) is researched in detail.At last, an instance system (FATS) is put out to prove the virtue of the DMS which researched in this paper.
