Abstract

One of the most active areas in database research has been the design of data models and query languages for the efficient retrieval of data. Multimedia/hypermedia pose new and challenging problems to database research. Some of the new research topics are related to:

The new types of data being considered (e.g., visual data).
The new kinds of interaction with the data (e.g. via hyperlinks).
The wide availability of data (often "unstructered", in the database sense) over the WWW.

The papers of this session cover some of these important issues:

Addressing the Contents of Video in a Digital Library This paper addresses the problem of models of storage and efficient retrieval of data in a digital video library.
Integrating Hierarchical Navigation and Querying An integrated form of querying and hierarchical navigation is described in this paper, which is intended for all kinds of users, including those with minimal familiarity with the database contents and schema.
Filtering Hypermedia Network by Using View Mechanism The authors propose a new object-oriented data model that supports a sophisticated view mechanism.

An overview of these and other issues will be given in this short talk. Our emphasis will be on declarative and visual query languages for multimedia/hypermedia.
