摘要

This study develops an integrated conceptual representation scheme for multimedia documents that are viewed to comprise an object-oriented database. It develops the necessary abstractions for the conceptual model and extensions to the RM/T relational model used as the search structure. It then develops a retrieval model in which the database search space is first narrowed down, based on user query, by an associative search. The associative search is followed by semantic and media-specific searches. A query language called SQLX is introduced to formulate these searches directly from the conceptual model. In SQLX, connector attributes replace join, and abstract data types enable use of objects and their methods in query formulation. The paper concludes with the description of a temporal model for time-dependent presentations and with the directions for future work.
