Treffer: A Java Application Programming Interface to a Multimedia Enhanced Object-Oriented DBMS

Advanced multimedia applications call for integrated DBMS support, i.e., the integrated modeling, management, and interactive presentation of persistent multimedia documents. Generic services for the presentation of multimedia documents have to be available at the database clients. This includes continuous data delivery, realization of presentation layout, synchronization enforcement, and an efficient interaction handling. In this paper, we propose a Java application programming interface (Java API) to a multimedia enhanced OODBMS. We follow a two-step approach: First, we implement access to persistent data managed by the core OODBMS. Second, we present the design of generic multimedia presentation services in the Java. This Java API enables database client applications to access and to present multimedia documents persistently stored in the database. With our Java API platform-independent access to multimedia information stored in database systems is possible.
