Subject: Computer Science
Level: Advanced
Description: Object-oriented technology is a growing market. Object-oriented analysis and design methods, programming languages and tools, new companies and products emerge in order to satisfy the need of more flexible and powerful data management.

The relational database products have been dominating the market since the 1980s. It has a strong formal background and fits many applications that require a powerful query language.

Relational database systems are based on two-dimensional tables were items appears as a row. An object can model everything, ranging from numbers to a person to an aeroplane. For expressing object structures in two-dimensional tables, complex interfaces are needed, to handle data manipulation correctly. The semantic mismatch between object-oriented programming languages and the relational data model has led to the development of an object-oriented database, which supports the object model.

This document describes the differences between relational and object-oriented database models. It also includes an evaluation of the object-oriented database product Objectivity.
