摘要：Over the past few years, XML has become the undisputable lingua franca standard both for semistructured data representation and exchange format over the Internet, and also content management in various ebusiness worlds, especially the B2B and B2C enterprise applications. However, most of these organisations still rely heavily on existing relational database management systems (RDBMS) to store and manage their structured data for daily critical business transactions. In fact, major database vendors, which also happen to be the giant software companies like Microsoft, IBM and Oracle, have ventured and taken great initiatives in researching and providing for a single solution to integrate these semistructured XML data with structured data in relational databases. Most importantly, it is estimated that during the next few years to come, more than 75% of ebusiness applications will implement XML technologies in their applications. Consequently, as more software applications are rapidly beginning to implement XML, there should be a growing need for XML middleware to efficiently integrating XML data at the frontend with a RDBMS at the backend. Hence, this research is aimed at providing a generic XMLbased framework, which is known as JXDB, that allows a user to use XML for dealing with semistructured data for creating, accessing or updating to existing heterogeneous relational databases that store structured data and vice versa. JXDB is designed to provide a generic and extensive XML middleware framework for integration between XML documents and heterogeneous relational databases.
