ABSTRACT
This paper presents an approach for transforming an XML schema we enriched in ODL (Object Definition Language) schemas. It is possible to realize the concepts of ODL in a model of XML schema, we propose to introduce an enrichment concretizing these concepts in the XML Schema models. We chose oriented object database as a target database because there are many common characteristics between XML and object-oriented model, thus the mapping from XML data into object-oriented databases is more interesting. Also the object-oriented data bases have become very widespread and acceptable and they offer an evolutionary approach, so we agree that it is time to develop a translation between XML and OO databases. The purpose of this article is to automate transformation process of an XML schema to an ODL database. Our work focuses on preserving semantics transformation of association relationships and we describe set of rules to create ODL classes from an enriched XML schema. The experimental study shows that the approach is feasible, and results are the same, the source database is transformed into target one without loss of data.
