Abstract: Most object-oriented databases can only be accessed by a programming language rather than a query language, although an ad hoc query facility is a desirable feature of such systems. In this paper, we present a way to process queries to extract data from a collection of interacting objects. We adopt the object-oriented paradigm to describe the operational semantics of queries given as expressions of a query algebra. An expression can be transformed into a collection of active objects performing... (Update)
