DESING AND IMPLEMENTATION OF VERSION COMTROL FOR THE QBOE MULTIMEDIA DATABASE SYSTEM

Abstract

In advanced applications, especially those in which a database has to support the design of a manufactured product, versions of objects have to be managed; that is , to keep different status of the same data, which is called historical versions. This requirement is inherent in applications that are exploratory and evolutionary. Version control in the multimedia document creation environment is similar to that in any design environment. In the paper, based on the object-orented data model, we design and implement version control for a Query-By-Object-Example multimedia database system, in which we consider data of typers text, drawings, images, audio, animation and videos. The system and the query language are both called Query-By-Object-example, since th euser-interface is through an objcet example.
