Product Description
Second Edition now available! Real-time systems programmers face unique challenges. Qualities such as execution speed and memory size are paramount in the development of real-time systems, and performance is a fundamental aspect of correctness in this domain. Given these constraints and requirements, it is fair to say that the development of real-time systems is more challenging than that of most software systems. Yet the lack of a standard notation and design process has discouraged embedded systems developers from adopting a revolutionary new approach to software design--object technology--that has produced clearly identifiable benefits in less specialized software applications. With the development and wide adoption of a standard notation, the Unified Modified Language (UML), real-time systems developers can now avail themselves of the benefits and advantages of object technology. UML is a 3rd generation modeling language which rigorously defines the semantics of the object metamodel and provides a notation for capturing and communicating object structure and behavior. It is particularly well-suited to modeling real-time and embedded systems.Real-Time UML is the introduction that developers of real-time systems need to make the transition to object-oriented analysis and design and modeling with UML. It covers the important features of the UML and shows how to effectively use the UML to model real-time systems. The book includes special in-depth discussions of finite state machines, object identification strategies, and real-time design patterns to help beginning and experienced developers alike. 0201325799B04062001

From the Author
My thoughts on Real-Time UML
I am gratified by the positive response for this book by the embedded and real-time community. I've been developing safety-critical real-time and embedded (RT&E) systems for almost 20 years, and have often thought that a book that integrated modeling concepts with the more commonly discussed real-time problems was needed. I strongly believe that object technology is not only mature enough to be used in RT&E systems, but that the growing complexity of these systems requires better ways of dealing with that complexity than traditional structured methods allow. The UML is a leap forward, unifying the best practices in object methodologies. Many of the companies to which I consult are using UML to effectively construct RT&E systems ranging from small 8-bit sized systems up to very large distributed systems with potentially hundreds of processors. This book is meant to be a gentle introduction to the UML and focus on the aspects of UML that are of particular concern to RT&E developers, such as how to identify objects, how to effectively use statecharts and state machines, and a process for using the elements of the UML to construct systems effectively. I hope you find the book helpful. Feel free to send me your comments and success stories.

Most Helpful Customer Reviews   4 of 4 people found the following review helpful: 2.0 out of 5 stars Not impressed., 28 Feb 2002 By A Customer Despite Mr. Douglass' impeccable credentials, I do not rate this book either as a book for learner/intermediate level or as a UML book for embedded specialists. To me, it is too expensive and he has a companion book on sale for you to buy too. Mr Douglass puts himself on record as a celebrant of the Rhapsody product from I-Logix. If you happen to use Rhapsody then good luck to you but if you use Rational Rose or one of the other tools, you will find missing many of the features he highlights as useful in real time systems. Examples would be pseudostates, instantiatable submachines, the 'dotted-line' notation for concurrency in state diagrams, the <<active>> sterotype. I thought sections 5.6 and 5.7 on representing and defining threads were pretty pointless really. Like a lot of this book, these sections shows how a yen for UML as a intellectual pursuit can replace coherent thinking about your actual application. Like the rider carrying the horse instead of the other way around. On the plus side, Section 4 on state machines was OK despite the Rhapsody-specific slant. Finally the ROPES design methodology advocated here: Boring, prescriptive and unrealistic in my view. I realise that I am up against the almighty Grady Booch in writing this indifferent review. Listen to him if you want. It's your money. I'll stick my neck out further. Why don't you buy the excellent Schaum's Outlines book 'UML' and a $95 copy of Sparx Systems' Enterprise Architect and get stuck in? You won't regret it.

I like how he introduces the problems of development and design that are unique to real time systems, and then demonstrates how, with the UML, one goes about modeling solutions to these problems. The discussion on patterns relative to real time systems is what really sets this book apart. Most of the current patterns work does not reach into this domain, and Bruce has done an excellent job of combining theory (in the world of patterns) with pragmatics (in the world of real time systems).

First because OO didn't show itself much valuable for dynamic systems, second because their usually is no OO language supported by our typical hardware. Then i read Real-Time UML. And i found a very simple, clear way to present and organize my design ideas. Furthermore, UML showed itself very efficient in detecting design error, refining some concepts. Now, each time i have to express my feelings, orientations, solutions, i use one or several of UML's diagrams. This is honnestly a must-read book, where any RT embedded system designer will find a good method to clear and refine things. It also shows itself very didactic in explaining the basics of Object Oriented Design. Impressive ! Comment Comment | Permalink | Was this review helpful to you?

Thanks to this book, I have finally taken the plunge with OOD for our latest safety critical embedded project. I am surprised at how gentle my induction has been.
