At the heart of the book are the functional areas of an industrial firm. Although the data structures are thereby designed according to functional area the integration principle of supra-functional processing of tasks occupies the foreground. This book aims to achieve both a scientifically-based procedural method and a practically relevant, tried and tested approach. The author's experience of developing and introducing integrated information systems in several large industrial firms is incorporated in the treatment presented.
