The Varlet database reengineering project has been started in 1995 at the Software Engineering Group, Department of Mathematics and Computer Science, University of Paderborn.

This project is continued by the Network-Centric Software Engineering Lab (NET-lab) at the University of Victoria. It is also the basis for the Reddmom project at the University of Paderborn.

Goals:

• Development of an adaptable, tightly integrated environment for information system reengineering
• Tool support for an explorative and evolutionary reengineering process
• Automatic generation of a middleware for object-oriented client/server information systems

Approach:

• Semi-interactive analysis of legacy information systems supported by a fuzzy/neural network.
• Legacy code analysis by cliche detection
• Flexible schema mapping by triple graph grammar specifications
• Object-oriented schema restructuring by graph rewriting
• Seamless integration of object-oriented client/server technology through a data access middleware and the Java ODMG 2.0-Binding
