Abstract

Abstract. We present a new approach to virtual, object-oriented, updateable views in object databases. Within this approach it is possible to include into a view definition information on user intents of view updates. These information have a form of procedures that overload default update operations performed on virtual objects. Due to procedures we support full algorithmic power of view definitions, which is essential for many applications. The proposed mechanism is based on the Stack- Based Approach to query languages in which query language is treated as a special kind of programming language and is operated in the similar manner. 1
