A logic framework for a semantics of object oriented data modelling
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
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
For efficient system specification development, it is very important that the developers can compose the development methods suitable for...
Versatile querying facilities for a dynamic object clustering model

A rigorous approach to schema restructuring
A problem of schema integration is that one cannot directly merge concepts that are intuitively the same but have...
Managing schema changes in object-relationship databases
Changing a database schema may affect existing data and application programs. Immediate data restructuring is a first usual strategy...
Behavioural constraints: Why using events instead of states
This paper focusses on the behavioural constraints of the IFO2 model, an extension of the semantic model IFO defined...
