QBE agent embedded in multimedia framework for contents-based retrieval

Recent progress in hardware has enabled the management of large amounts of images, video, audio, or a combination of them. The growing need for retrieving the contents of such data is a natural conclusion of the requirement for database systems. Conventional database systems do not provide sufficient flexibility in managing data, because of the inability to manage spatio-temporal relations, to recognize contents in multimedia data, and to allow various types of query representation based on QBE for enabling intuitive representation of the query condition. These three deficiencies relate to all of the components of the database system. That is, the first issue depends on the data model or indexing, the second on DBMS construction and the last relates to the user interface. Therefore, none of them can be neglected for discussing all possible cases of content-based retrieval. We have implemented a user interface design for an effective content based retrieval system which relates to a distributed multimedia network environment. We examine the network for the distance education multimedia framework
