The MPEG-7 Multimedia Database System (MPEG-7 MMDB)

Broadly used Database Management Systems (DBMS) propose multimedia extensions, like Oracle’s Multimedia (formerly interMedia). However, these extensions lack means for managing the requirements of multimedia data in terms of semantic meaningful querying, advanced indexing, content modeling and multimedia programming libraries.In this context, this paper presents the MPEG-7 Multimedia DataBase System (MPEG-7 MMDB). The innovative parts of our system are our metadata model for multimedia content relying on the XML-based MPEG-7 standard, a new indexing and querying system for MPEG-7, the query optimizer and the supporting internal and external application libraries.The resulting system, extending Oracle 10g, is verified and demonstrated by the use of two real multimedia applications in the field of audio recognition and image retrieval.
