NIVERSITY Support for Object - Oriented Database Schema Design
نویسنده
چکیده
Even with the help of present schema design tools (e.g. graphical editors, EER model techniques, etc) the task of constructing any non-trival object oriented database schema (OODB) is immense. This paper describes a system, TYPSYS, which automatically produces a type hierarchy from information about the leaf object types (types at leaf level of the hierarchy) which are visible from the database requirements. The system can also rationalize any changes to the type hierarchy.

متن کاملSubtyping : conceptual and logical issues
Subtyping is an important feature of semantic approaches to conceptual schema design and, more recently, object-oriented database design. However the relational model does not directly support subtyping, and CASE tools for mapping conceptual to relational schemas typically provide only very weak support for mapping subtypes. This paper surveys some of the main issues related to conceptual speci...
متن کاملOODB Design with EER
In contrast to the conventional methodology of object-oriented program design focused on the interaction of objects, object-oriented database design should be based on the representation of objects. We put more emphasis in the application semantics pertinent to the structures of, relationships between, and constraints on objects than operations on the objects. Enhanced Entity-Relationship (EER)...
