Abstract

OODBMS are often used for complex data whose structure is likely to change over time, yet the problem of schema updates has not been completely solved by any commercial or research OODBMS. This tutorial describes the schema modification problem and why it is important, what is really offered by products, what a good solution would be like, and whether we are likely to see it soon.

The tutorial reviews several commercial OODBMS products that provide facilities for updating the schema, namely: Gemstone (Servio Corporation), ITASCA(Itasca), 02(02Technology), ObjectStore (ObjectDesign), Ontos (Ontologic) and Statice (Symbolics). It also describes the solutions proposed in some experimental research prototypes and the open problems that remain.
