Abstract

Robust and portable software design and implementation based on an object-oriented database interface P. Heinckiens, H. Tromp & G.

It hides the underlying data storage from the application developer and allows him to model his problem domain and to design the application at a much higher level of abstraction Persistent objects can be treated in exactly the same way as temporary objects and persistent class hierarchies can be designed. The practical use of the database interface is also illustrated : a general purpose data management and entry system is presented, which also hides the graphical user interface.
