Come, Let's Play (eBook, PDF)

Scenario-Based Programming Using LSCs and the Play-Engine

• Format: PDF

Produktbeschreibung

The play-in/play-out method and tool presented in this book is a powerful new approach to software and systems engineering and modeling based on formal methods and program semantics. The life sequence charts (LSC) as the language of this approach generalize the message sequence charts of UML and are presented in this book for the first time in a coherent and systematic way.

The method described is fascinating from the scientific point of view. The associated play-engine tool available from the authors' Web site has broad appeal to professionals in software engineering, systems engineering, and modeling and simulation.

Autorenporträt

David Harel is the Dean of the Faculty of Mathematics and Computer Science at the Weizmann Institute of Science in Israel. He is also co-founder of I-Logix, Inc., Andover, MA, and of SenseIT Technologies, Ltd. (DigiScents Israel). His research interests are in theoretical computer science (especially computability, automata theory and logics of programs), and in software and systems engineering (especially specification and modeling, object-oriented analysis and design, and visual languages), as well as the aesthetic layout of diagrams, clustering algorithms and the synthesis and communication of smell. He is the inventor of the language of statecharts (1983), was part of the team that designed the Statemate (1984-1987) and Rhapsody (1997) tools, and was co-inventor of LSCs (1998). His work is central to the behavioral aspects of the UML. He devotes part of his time to expository work: In 1984 he delivered a lecture series on Israeli radio, and in 1998 he hosted a series on Israeli television; some of his writing is intended for a general audience (see, for example, Computers Ltd.: What They Really Can't Do , Oxford University Press, September 2000). He has received a number of awards, including ACM's Karlstrom Outstanding Educator Award in 1992, and the 1997 Israeli Prime Minister's Award for Software. His book, Algorithmics: The Spirit of Computing (Addison-Wesley, 1987, 2nd. edn. 1992) was the Spring 1988 Main Selection of the Macmillan Library of Science. He is a Fellow of the ACM and of the IEEE.

Rezensionen

"The design of reactive systems is one of the most challenging problems in computer science. This books starts with a critical insight to explain the difficulty of this problem: there is a fundamental gap between the scenario-based way in which people think about such systems and the state-based way in which these systems are implemented. The book then offers a radical proposal to bridge this gap by means of playing scenarios. Systems can be specified by playing in scenarios and implemented by means of a Play-Engine that plays out scenarios. This idea is carried out and developed, lucidly, formally and playfully, to its fullest. The result is a compelling proposal, accompanied by a prototype software engine, for reactive systems design, which is bound to cause a splash in the software-engineering community." -- Moshe Y. Vardi, Rice University, Houston, Texas, USA

"Scenarios are a primary exchange tool in explaining system behavior to others, but their limited expressive power never made them able to fully describe systems, thus limiting their use. The language of Live Sequence Charts (LSCs) presented in this beautifully written book achieves this goal, and the attached Play-Engine software makes these LSCs really come alive. This is undoubtedly a key breakthrough that will start long-awaited and exciting new directions in systems specification, synthesis, and analysis." -- Gérard Berry, Esterel Technologies and INRIA, Sophia-Antipolis, France

"The approach of David Harel and Rami Marelly is a fascinating way of combining prototyping techniques with techniques for identifying behavior and user interfaces." -- Manfred Broy, Technical University of Munich, Germany
