In this paper we address the problem of schema evolution in object-oriented database systems. Most currently available database prototypes either completely lack schema evolution facilities, or offer a restricted set of special purpose schema evolution operators supporting simple schema changes. Our approach is different. We consider schema objects as objects like others and have the meta schema fully available at run-time. Thus any operator of our object manipulation and query algebra can be applied to meta-objects ..
