Flexible Database Transformations: The SERF Approach
نویسندگان
چکیده
Database transformations is a critical task that occurs in many different domains. Schema evolution is one important class of problems for database transformations. In our work, we use existing technology and standards (ODMG, OQL, basic schema evolution primitives) to bring flexibility, extensibility and re-usability to current schema evolution systems, thus allowing the users to conveniently specify any customized transformation of their choice. We also investigate the re-usabilty of our framework to other applications beyond schema evolution such as web re-structuring.

With current database technology trends, there is an increasing need to specify and handle complex schema changes. The existing support for schema evolution in current OODB systems is limited to a pre-defined taxonomy of schema evolution operations with fixed semantics. Given the variety of types, complexity, and semantics of transformations, it is sheer impossible to a-priori provide a complet...
