Abstract

In this paper we present the primary concepts of PBASE, a prototype Object Oriented Database System. PBASE is intended to support the needs of engineering applications with specific reference to structural engineering. To address the engineering requirements the object oriented data model used in PBASE incorporates several enhancements including Schema Evolution, Composite Objects, Declarative Methods and Version Management. Schema evolution allows dynamic changes to the class definitions and the class lattice. Composite objects support the is-part-of relationship between assemblies and components. Declarative methods introduce semantics into objects while version management supports the tracking of objects' versions d alternatives as they evolve during the design process.
