To build information systems today, a multimedia database system is needed which supports both structured data and media data. Because these two kinds of data differ significantly in their characteristics, the extension of traditional databases towards the support of media data is a very tedious task. As an alternative, the intelligent coupling of specialized component systems, i.e. traditional databases, media storage systems, and media retrieval systems, can be used to build a multimedia database system. In this paper, a global-schema construction methodology for a federation of these component systems is presented. It allows the unrestricted extension of the global schema. Furthermore, a schema-independent query processing module for global schemas constructed with this methodology is designed. It can handle the given distribution pattern. In addition, it explores the functionality of media retrieval systems concerning search functions and result restrictions.
