We describe a (meta) formalism, called Data Modelling Logic (DM logic), for defining a variety of (object oriented) data...

A declarative query approach to object identification

0
Object identification in data models, especially in semantic, Entity-Relationship, and Object-Oriented data models is studied. Various known approaches to...

Object-oriented meta modelling

Most temporal data models have concentrated on describing temporal data based on versioning of objects, tuples, or attributes. The...

View-centered conceptual modelling

Inheritance is one of the central concepts of object-oriented programming (OOP). In object-oriented design therefore a part of the...

IO2 an algorithmic method for building inheritance graphs in object database design
