Abstract

The extended version of SQL+D presented here takes multimedia to its ultimate realm: the third dimension, allowing the user to explore the data in a virtual reality environment and display VRML files as data objects. Unlike the limited number of efforts in this area, SQL+D goes beyond constructing 3D bar charts. It allows truly interactive environments dynamically specified by the user in a query and constructed from data extracted from the database. Multimedia presentations are usually specified for a fixed set of elements. When dealing with database queries, the specific elements are unknown until the answer set is obtained. We present the syntax of an improved version of SQL+D that allows a user to specify complex generic temporal presentations within the query itself. We have implemented most of our proposed extension
