120 ;;Quote: arbitrary changes to database schemas are needed for a design environment
120 ;;Quote: what happens to old objects and their programs when a type definition changes; assumptions will no longer hold
121 ;;Quote: a type specifies behavior, i.e., a set of operations, properties, and constraints
121 ;;Quote: types, operations, and properties are themselves objects defined by a type
121 ;;Quote: properties are objects which define relations to other objects, e.g., 'works-for'
121 ;;Quote: handle modified types by defining error handlers for each version; these handlers fixup an old version's behavior
