Research On Converting XML-Schema Data To Object-Relational Data

XML is rapidly emerging as the standard for representing and exchanging data in World Wide Web. It becomes more and more necessary to study how to store and query XML data effectively. There are many strategies for storing XML documents, using (object-) relational database to store XML document is one kind of the strategies.The paper discussed a new mapping method from XML-Schema to the object-relational database and discussed its basic mapping rules and a algorithm based on DOM-Chart model in details. The new DOM-Chart model is defined according to the modification of the DOM tree model. The primary mapping algorithm in which the target schema is described by concept model is drawn up according to the new DOM-Chart model. The steps of converting concept model to physical model and the steps for storing XML data in object-relational database are also listed briefly.The algorithm of mapping from XML-Schema to object-relational creates object-relational pattern irrelevant to RDBMS. Here, it is called...
