An architecture for the integration of multimedia heterogeneous data sources

The main focus of the paper is the design of a system which integrates data from heterogeneous multimedia repositories in a single, unified database view, in order to build a multimedia information system capable of integrating data that resides in different data base systems as well as in a variety of non-database data servers. We describe the object oriented data model used as a common model from the wrapper/mediator system, so providing a simple mechanism for enabling the integration while maintaining the independence of the repositories and providing a semantic description of the extracted data.
