Abstract

With the increasing amount of XML used in web applications forrepresenting and exchanging information, researchers have proposeddifferent methods of using relational database to store and manageXML data. The model-mapping methods do not require DTD so thatfixed database schemas can be used. In this paper, we present a newmodel-mapping method called INode*. This method is based on anumbering scheme for mapping XML data into relational databases. Itenables quick retrieval of ancestor-descendant relationshipsbetween elements in XML by simple calculations. Experiments showthat INode* can reduce the storage requirement while having abetter query performance in comparison to several othermodel-mapping methods.
