Abstract

In this paper, we extend the schema evolution operations of a schema manager called Omnis, considering semantical aspects. The proposed object view integration method (Ovi), is intended to help the DBA and Omnis users in integrating new classes in an oodb schema, with automatic enforcement of database consistency and non redundancy. Ovi uses the generic data model of Omnis as conceptual model to gain independence from the persistent object-oriented programming language. It also exploits an OO methodology to provide extensibility. It is implemented in C++.
