Object-Oriented Data Model Concepts

A key concept of any database system is the data model it is based upon. Object-oriented data models (OODM) try to blend object-oriented concepts as they first emerged in programming languages with concepts from traditional (e.g. network or relational) data models, and at the same time respond to new requirements as they are posed by a variety of “nonstandard” application areas like CAD/CAM, geographic information systems, or office information systems. They are primarily used in object-oriented database management systems (OODBMS ), but even traditional systems are about to adopt some of their features.
