Transformation Rules from Semi-structured XML Documents to Database Model

XlML semi-structured documents provide a flexible and natural way to capture data. More often, users exchange documents with others or reuse their data in a wide range of tasks. A direct consequence is a growing need to manage semi-structured documents and to gain conventional database functionality. The aim of our research I S the development of a comprehensive capturing and mapping data system that ensures flexible and well-adapted information capture and at the same time efJicient information retrieval. A transformation process allows the mapping between the semi-structured document model and the traditional database model. It handles data extraction and data restructuring and deals with data mapping rules to feed traditional databases.
