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
