| Abstract(in English) | In this work, we discuss the theoretical foundation for type hierarchy of complex objects to extend modelling concepts, semantics and constraints. Complex objects consist of entities and data-structure instances. We assume general constructions of data structures, i.e., not only sets and tuples but, any structuring operators are allowed. Our discussion uses an instance-based data model and each instance has its own intentional information called type schemes. Since there may be infinite complex type information to each instance, we explore simplified description in such a way that type schemes contain only least general types. We show the finiteness property of such description. The heart of our approach exists in semantic orders for of complex objects. |
