|Summary||Although multimedia information technology has become popular, conventional database systems do not offer adequate support for the modeling, indexing, and manipulation of multimedia data. Database management systems need to be extended if they are to handle multimedia information like audio and video. In this paper we present an approach to extend the data model of an object-oriented database programming language called DOOR by means of a meta-object protocol to implement the classes for multimedia objects. In particular, we model the different multimedia presentations (mostly with different characteristics) of a real-world entity as a single object which plays different roles. Moreover, we also propose different ways of using views to provide the right level of abstraction of the resources and data representation.|
