Based on the proceedings of a workshop held at the Appin in August 1985, this book discusses the issues of data abstraction. It introduces the concept of inheritance as a method of polymorphic modelling. It also discusses the issues of controlled access to large scale data in a concurrent and distributed persistent environment.
