The book provides an introduction to software engineering for distributed systems. Concepts which are essential for the development of distributed programs are described in detail. It explains how software engineering methods for both non-distributed and distributed programs can be combined in order to use their advantages. The result is called "subject oriented programming". It combines asynchronous parallel processes, i.e. threads and object oriented concepts. This hybrid approach makes it easier to design and implement distributed software systems and therefore increases the efficiency of the software engineering process. The book is one of the first publications on distributed software system design. The book provides an introduction to sotfware engineering for distributed systems.

Methoden der Programmierung "verteilter" Software gewinnen angesichts der zunehmenden Vernetzung von Computern an Bedeutung. Dieses Buch gibt eine Einführung in das Thema "Distributed Software Design" und stellt die verschiedenen Ansätze anhand von Beispielen vor. Ein Buch für Informatik-Studenten, aber auch für den Software-Entwickler, der sich in die Methoden der Programmierung verteilter Software einarbeiten möchte.
