Migration from relational to object-oriented databases

This paper examines the issues involved in the migration of database technology towards object-orientation. This includes issues of schema translation, data migration and the consideration of the whole database system including client programs. In addition, this paper reports some early results from a long-term project to provide support for the migration of data and meta-data from a relational to an object-oriented database. The initial tool processes the schema of a relational database and presents it to the user as the equivalent object-oriented schema. The result of this processing is an initial version of the object schema and requires user intervention in the naming of new abstract classes built by the system.
