Data Repository and Data Layer in Hyperbook System Using XML RDBS

In this paper we consider the use of XML technology for the data repository and data layer in the Hyperbook system. We propose the Hyperbook data layer (HBDL) for Hyperbook data repository using RDBMS. In HBDL the transformation technique from XML to relational data is the schema independent. The approach observes an XML file as consisting of terms of hierarchical data structure. Each node of data is made up of label and data fields. Each node is converted to a record in a relational table.
