In earlier work (Roddick 1993; Roddick, Craske and Richards 1993) a taxonomy for schema evolution is proposed which uses a transaction time meta relation approach; i.e. previous schemata may be constructed through temporal rollback of the meta relations. Many schema change requirements will involve composite operations and ....
