Lenny Hoffman, Todd Stavish, Dr Nic Caine, Brian Clark. Objectivity, Inc.
Dynamic Schemas in object database management systems (ODBMS)
Through the lifetime of a system processing and data requirements change resulting in changes to the underlying object model. Managing these changes without having to take the application down is a key requirement in many of these systems. This paper discusses ways to manage these changes.

Richard Lingeh, Principal Consultant, Versant
Schema Builder 2nd Best ODBMS.ORG Pattern Awards!
This paper presents 1 Pattern which allows any further evolution of a database after a complete modification of the client application model to be done by a separate schema process and not by the client application or by the schema it generates. This separate process generates a database schema that matches the complex evolving client application model.
