DDL = DML? An Exercise in Reflective Schema Management for Chimera

We discuss the basic principles of a reflective representation of application schemas using a subset of Chimera. We show how application schemas can be modelled as a set of Chimera objects when an appropriate meta schema has been defined. The semantics of schema evolution can then be defined by mapp...
