A typed, object-oriented, temporal constraint system is presented. The constraint programming paradigm is based on temporal Horn clause logic. If differs from executable temporal logic programming paradigms in that it...

Multimedia databases include many types of new data. One common property of these data items is that they are very large. We exploit the concept of transformational representations to logically store images without th...

An object-oriented database provides persistent storage for a large number of objects. These objects may be very small, and the access patterns are likely to be not as uniform as the mostly sequential reads and writes...

In this paper a class-based logic language for object-oriented databases which is called CLOG is described. CLOG is based on many sorted horn clauses with concept of classes, objects, object identity, multiple class m...

This paper describes an approach to the support of interface objects in an object-oriented database, and outlines some of the consequences of representing interface data as database objects. Existing architectures for...

This paper investigates an algorithm for semantic query optimization for object-oriented databases (OODBs). Semantic query optimization is accomplished by applying transformation rules that use semantic integrity cons...
