The Varlet database reengineering project has been started in 1995 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
