Semantics of time-varying attributes and their use for temporal database design
Based on a systematic study of the semantics of temporal attributes of entities, this paper provides new guidelines for...
Handling change management using temporal active repositories
Business Re-engineering requires frequent changes in the enterprises' information systems, however the current technology of data dictionaries is not...
A graphical query language for temporal databases
This paper addresses the issue of visual query formulation for temporal databases. We introduce a number of visual constructs...
Binary representation of ternary relationships in ER conceptual modeling
Our paper seeks to provide an analysis of ternary relationship logic with an objective of identifying whether they can...
Variable sets and functions framework for conceptual modeling: Integrating ER and OO via sketches...
In the paper a graph-based specification language for semantic modeling is proposed. It is as handy as conventional graphical...
Unifying modeling and programming through an active, object-oriented, model-equivalent programming language
The intricate and complex structure of existing advanced database applications results in part from poor integration of existing models...
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
The conceptual clustering model (CCM) that we have defined in is an extension to current object-oriented models; it...
