User-Driven Mapping of XML Schemas to SQL

The use of relational databases to store and query XML data is a very attractive way to increase efficiency of techniques for managing these data. Due to the big differences between the relational and XML data models, it is essential to create mapping between the XML and the relational schema. In the presented work we study user-driven techniques for deriving relational database schema from a given XML Schema (expressed in XML Schema language) and apply the acquired knowledge in implementation of an experimental tool which uses the selected technique to derive relational database schema with assistance of a database designer in a user-friendly GUI
