9.3) OTGen (Carnegie Mellon University/UMass Amherst) (Research Systems - OO Data Model - Object-oriented Databases And Vendors)

OTGen is a design for a system to support schema evolution in
object-oriented databases. The chief contribution of OTGen is support
for programmer extensibility of transformation functions to allow a
system to support a wide range of schema changes, not just those that
can be easily automated. While OTGen was never implemented, it is
based on the implementation of TransformGen, a system to support the
evolution of the specialized databases used by Gandalf programming
environments. For more information on OTGen and TransformGen, please

to Database Reorganization", in Proceedings of the Joint ACM
