DATA MODEL AND ARCHITECTURE OF MULTIMEDIA DATABASE FOR ENGINEERING APPLICATIONS

This papaer presents a data model and the database system architecture to handle multimedia data, especially video (or image sequence) data. A new scheme ''AIS diagram'' is introduced, by which all informations about entities and relationships among bitmap frames or textual infor mations are described in a uniform way. We focus on the integration of engineering data. The most important problem to be solved is how to c apture the ''objects'' in each frame and to represent them in the data model. For this purpose we propose ''physical cut'' and ''logical cut '' as a unit of information in image sequences and, using those concep ts, we developed a prototype system for multimedia data processing on a conventional database system.
