An object-relational database system for the interactive multimedia

A practical and effective data model for interactive multimedia is provided in the authors' project. It is shown that the data model is not only adequate to represent various types of media entities including audio, video, image and text, but also competent for facilitating hypermedia relationships among different entities. Based on such a data model, they have designed and developed an object-relational multimedia database infrastructure, with a number of useful schemas for supporting multimedia services. Apart from standard authoring, editing, and searching/querying features, advanced options such as hypermedia navigating and browsing are also supported in the object-relational multimedia database (ORDB). A prototype of the proposed ORDB is being implemented for interactive multimedia applications.
