Document Storage And Retrieval System Protocols To Access Multimedia Data

Multimedia documents are complex accumulations of content portions that belong to different information types. Each information type needs dedicated tools that allow for generation, modification and presentation. The object oriented concept of modelling data seems to be a preferred one in the field of multimedia documents as can be seen within standards specification and proprietary approaches. Although it is partly possible to extend relational database technology to satisfy the needs of multimedia documen storage. There are systems more suitable as a base for a multimedia database system which support for the representation of the needed information types and the extensibility. RDA or DFR design concepts focuses on specifications and lower layer protocols supporting isochronous transfer of data.
