Layered approach to multimedia database systems

Multimode database systems are becoming increasingly important as organizations accumulate more multimedia data. There are few solutions that allow the information to be stored and managed efficiently. Relational systems provide features that organization rely on for their alphanumeric data. Unfortunately, these system lack facilities necessary for the handling of multimedia data - things like media integration, composition and presentation, multimedia interface and interactivity, imprecise query support, and multimedia indexing. One solution suggested for storage of multimedia data is the use of object-oriented database management system as a layer on top of the relational system. The layer adds required multimedia functionality to the capabilities provided by the relational system. A prototype solution implemented in Java uses the facilities offered by JDBC to provide connection to a large number of databases. Java Media Framework is used to present the video and audio data. Among the facilities provided are image/video/audio display/playback and extension of SQL to include multimedia operators and functions.
