Software Design Methods
for Concurrent and Real-Time Systems
by Hassan Gomaa
George Mason University
Published by Addison-Wesley Publishing Company
as part of the SEI Series in Software Engineering
ISBN # 52577
In this book, Gomaa outlines the characteristics of
concurrent, real-time, and distributed systems, describes
the concepts most important in their design, and surveys the
design methods available for them. Drawing on his
experience in industry, he takes two related object-oriented
methods -- ADARTS (Ada-based Design Approach for Real-Time
Systems) and CODARTS (COncurrent Design Approach for Real-
Time Systems) -- and shows in detail how they can be
applied.
The author first introduces the reader to real-time and
concurrency concepts, and reviews the background in software
design and development needed for the balance of the book.
He then describes a number of methods that can be used for
real-time and concurrent system design, comparing them
through application to a common problem. Methods described
include Real-time Structured Analysis and Design, Jackson
System Development, Parnas' Naval Research Lab/Software Cost
Reduction Method, and Object-Oriented Design. For each
design method treated, the author presents the concepts on
which it is based, the steps used in its application, and an
assessment of its effectiveness. Gomaa then focuses on
ADARTS, a practical method developed by the author and
proven over time, and CODARTS, which contains the author's
latest ideas on software analysis and design. The final
part of the book features practical case studies in which
the ADARTS and CODARTS methods are demonstrated.
Highlights
* Provides a basic understanding of concepts and
issues in concurrent system design, while
surveying and comparing a range of applicable
design methods.
* Elaborates two object-oriented design methods for
the effective design of concurrent and real-time
systems, including the design of distributed
applications.
* Describes a practical approach for applying real-
time scheduling theory to analyze the performance
of real-time designs.
This book is valuable for software designers and developers
faced with the growing need to design interactive,
concurrent, real-time, and distributed systems with state-
of-the-art software design methods.
