Inheritance in Computer-Aided Design Databases: Semantics and Implementation Issues

Object-oriented models are advocated as good ways to describe semantic-rich application domains such as computer-aided design. We describe the role and limitations of conventional type-instance inheritance for modeling CAD data, and propose a new semantics based on instance-to-instance inheritance. New algorithms for object clustering, buffer management, and on-line back-up are described that exploit the new inheritance semantics for more efficient run-time performance.
