Software Systems Architecture: Working With Stakeholders Using Viewpoints and Perspectives ReviewWhen it comes to the systems or software architecture, I subscribe to Tom Demarco's definition: "An architecture is a framework for the disciplined introduction of change." (http://www.systemsguild.com/GuildSite/TDM/Architecture.html). And while most of the job postings matching "architect" these days talk about the need for writing and testing code, there is a growing awareness in the industry that in order to build a resilient enterprise system an organization must look beyond design patterns and coding idioms. In addition to the technical challenges, building large enterprise system requires effort of many professionals during an extended period of time. This brings other non-technical risks into the picture.
This is one of the better books covering many issues that comprise System Architecture discipline in the light of their personal experience. The authors introduce us to an approach for partitioning architecture using Viewpoints (behavioral characteristics, e.g. Functional, Information, Concurrency, Development, Deployment, Operational) and Perspectives (nonfunctional aspects, e.g. Security, Performance and Scalability, Availability and Resilience, Evolution).
The first half of the book describes the discipline of Application Software Architecture, the second half contains two catalogs, one for Viewpoints and the other for Perspectives. Both catalogs describe concerns, artifacts (models), problems and pitfalls when focusing on a viewpoint or perspective.
I would qualify this book as a companion and reference for a beginner through intermediate level. It gives an excellent overview of what a system architect has to go through day in and day out to achieve success. The book contains a wealth of advice on what to pay and not pay attention to in any particular stage of the architectural development. The authors clearly speak from personal experience. Their examples are always to the point, although a bit sketchy with respect to details on techniques and artifacts and how to develop and use them. Considering the site of the volume, the authors did an excellent job balancing width and depth of coverage: trying to cover such a vast discipline in detail in a 500+-page book is not possible.Software Systems Architecture: Working With Stakeholders Using Viewpoints and Perspectives Overview
Software Systems Architecture is a practitioner-oriented guide to designing and implementing effective architectures for information systems. It is both a readily accessible introduction to software architecture and an invaluable handbook of well-established best practices. It shows why the role of the architect is central to any successful information-systems development project, and, by presenting a set of architectural viewpoints and perspectives, provides specific direction for improving your own and your organization's approach to software systems architecture.

With this book you will learn how to

Design an architecture that reflects and balances the different needs of its stakeholders
Communicate the architecture to stakeholders and demonstrate that it has met their requirements
Focus on architecturally significant aspects of design, including frequently overlooked areas such as performance,resilience, and location
Use scenarios and patterns to drive the creation and validation of your architecture
Document your architecture as a set of related views
Use perspectives to ensure that your architecture exhibits important qualities such as performance, scalability, and security

The architectural viewpoints and perspectives presented in the book also provide a valuable long-term reference source for new and experienced architects alike.

Whether you are an aspiring or practicing software architect, you will find yourself referring repeatedly to the practical advice in this book throughout the lifecycle of your projects.

Modeling Embedded Systems and SoC's: Concurrency and Time in Models of Computation (Systems on Silicon) ReviewThe writer of this book, Dr. Axel Jantsch, is a professor at the Royal Institute of Technology in Stockholm, Sweden. As a postgraduate student at the Technical University of Denmark, I have participated Dr. Jantsch's course whose curriculum was dictated by this book.
Dr. Jantsch is a splendid lecturer and his a pioneer in his comprehensive, yet highly-readable, cover of modelling technieques for embedded systems. The book covers in depth notions such as final state machines, petri nets, as well as the untimed, timed and synchronous computation models. Dr. Jantsch does not, unlike other sources, sticks only to the formalism related to the modelling, but also includes "real life" examples that make the reader apprieciate what model of computation is the more optimal for his modelling aims.Modeling Embedded Systems and SoC's: Concurrency and Time in Models of Computation (Systems on Silicon) Overview

Systems Engineering Principles and Practice (Wiley Series in Systems Engineering and Management) ReviewI have just completed the JHU program in Systems Engineering. This book is the foundation for the curriculum and is a very readable, solid overview of Systems Engineering. All phases of the system life-cycle are introduced and tied together to truly illustrate the process. The book focuses on processes, the tools used will change, but good Systems Engineering will stay the same. The process to derive good requirements that are able to be implemented and tested are the same regardless of technology or field.Systems Engineering Principles and Practice (Wiley Series in Systems Engineering and Management) OverviewSystems Engineering Principles and Practice is a national standard textbook for the study of traditional systems engineering for advanced undergraduate and graduate students.It addresses the need for an introductory overview, first-text for the development and acquisition of complex technical systems. The material is well organized, readable and fundamental to learning how to think like a systems engineer and carry out best practices in the field. Since systems engineering is still developing as a discipline, there have been new concepts and practices that have entered the field since the text was published in 2003. As an increasing number of students have used the text, topics have been discovered that would benefit from expansion, integration and clarification.
The proposed second edition will be developed by colleagues of the original authors to upgrade this unique interdisciplinary guide to systems engineering to maintain relevance and currency in this rapidly changing and demanding field.

Abstract State Machines: A Method for High-Level System Design and Analysis ReviewThis is a well written good about an interesting, sensible formalism. I haven't tried using any of it in my line of work yet, but I'm pretty sure I will. Abstract State Machines (ASMs) are based on guarded, synchronously concurrent state transitions, with state effectively defined as a (finite) set of named, finite relations. The core of the formalism seems very simple and elegant and lends itself to clear, concise models at both high and low levels of abstraction. I believe it is more readily comprehended by practicioners than purely algebraic and / or functional approaches, being firmly rooted in the notion of state, operational abstract execution runs and state changes.
They models can be designed in a modular and composable manner in a natural way. The book gives a clear, rigorous account of it all, is readable and well organized, and positively loaded with helpul examples and references. My only complaint is that fully asynchronous (i.e. distributed) systems seem to get somewhat of a short thrift.
Overall, I am really excited about this stuff, and looking forward to a time when all system development can be undertaken and supported with such elegant, refinable models, as opposed to the hodgepodge scripting-language-centric mess that is the current practice.Abstract State Machines: A Method for High-Level System Design and Analysis OverviewThe systems engineering method proposed in this book, which is based on Abstract State Machines (ASMs), guidesthe development of software and embedded hardware-software systems seamlessly from requirements capture to actual implementation and documentation. The method bridges the gap between the human understanding and formulation of real-world problems and the deployment of their algorithmic solutions by code-executing machines. Within a single conceptual framework it covers design, verification by reasoning techniques, and validation by simulation and testing. ASMs improve current industrial practice by using accurate high-level modeling and by linking the descriptions at the successive stages of system development in an organic and efficiently maintainable chain of rigorous and coherent system models at stepwise-refined abstraction levels. In several industrial projects the ASM method has proven its superiority compared to the popular UML methodology when designing complex parallel or dynamic systems.This book combines the features of a textbook and a handbook: the reader will find detailed explanations, proofs, and exercises as well as numerous examples and real-world case studies. Researchers will find here the most comprehensive description of ASMs available today and professionals will use it as a "modeling handbook for the working software engineer." As a textbook it supports self-study or it can form the basis of a lecture course. The book is complemented by a CD containing the whole book text, additional course material, solutions to exercises, and additional examples. Even more information can be found on the related website maintained by the authors: http://www.di.unipi.it/AsmBook/

Microprogrammed State Machine Design ReviewMy first job in industry, back in the 1970s, was writing instruction set microcode for a mainframe processor, back before the RISC revolution. Then, through the 1980s, bit-slice processors appeared in everything from graphics controllers, to disk and network interfaces, to DSP applications of every kind. Between the RISC trend starting in the late 1980s and the centralization of processor design in a few major corporate labs, however, microcoded control was nearly forgotten.
With the rise of FPGA processing, microcoded control deserves another look. I find it ideal in cases where a problem is too big, complex, or fast-changing for hand-coded state machines to be practical, but where unusual hardware requirements can't be met with assembly programming. Microcoded control fills that middle ground nicely, with efficiency approaching a state machine's and with ease of use and modification close to that of regular programming. If you want a thorough introduction to microcoded logic design and controllers, this book does the job amazingly well.
Unfortunately, parts of the content have aged badly. Even in 1993, when this was first published, microcode was already old-school. Many of the bit-slice products and controllers, including the venerable 2900 family, were vanishing from the market even then - so chapters that describe such logic families are historical documents, at best. This book's real value lies in describing how microcontollers work, allowing modern logic designers to resurrect what was good in them and create controllers of their own, tailored to modern needs.
If you already have a firm handle on logic design basics but find your control logic getting too convoluted and unmaintainable, give this a shot. It will show you a disciplined but highly adaptable way to implement your control plane. You have too much else to do in filling a mega-LUT FPGA to let your controller take up your time.

It provides practical techniques and alternatives for designing solutions to data processing problems both in commerce andin research purposes. It offers an excellent introduction to the tools and elements of design used in microprogrammed state machines, and incoporates the necessary background in number systems, hardware building blocks, assemblers for use in preparing control programs, and tools and components for assemblers .The author conducts an in-depth examination of first- and second-level microprogrammed state machines. He promotes a top-down approach that examines algorithms mathematically to exploit the simplifications resulting from choosing the proper representation and application of algebraic manipulation. The steps involved in the cycle of design and simulation steps are demonstrated through an example of running a computer through a simulation. Other topics covered in Microprogrammed State Machine Design include a discussion of simulation methods, the development and use of assembler language processors, and comparisons among various hardware implementations, such as the Reduced Instruction Set Computer (RISC) and the Digital Signal Processor (DSP). As a text and guide, Microprogrammed State Machine Design will interest students in the computer sciences, computer architectects and engineers, systems programmers and analysts, and electrical engineers.

Architecture and Principles of Systems Engineering (CRC Complex and Enterprise Systems Engineering) ReviewThis text is a broad high level survey of systems engineering in the age of model-driven system development. Looking at the table of contents the coverage is extensive, but the depth on any given topic is pretty shallow. If you are a university student who hasn't had any exposure to systems engineering concepts (or software engineering concepts for that matter), then this text isn't a bad introduction to the terminology, (some of the)tools and process descriptions in modern systems engineering, especially if coupled with a project-based course where you can have a chance to apply some of these concepts directly. For such an audience, add one star to my rating. If, on the other hand, you are a practicing systems engineer (or software engineer), even if you're not all that familiar with the model-driven systems engineering paradigm, then this text is likely to come up a bit short, given its lack of depth on any given topic. For this second group of potential readers, take one star away from my rating. I was going to be cheeky and say that this is a great book for talking about systems engineering, but not so much if your interest is in doing systems engineering.
The description on the back cover is definitely over-hyped - publisher's perogative, I guess. You will not learn the obstacles, both technical and cultural, that model-driven systems engineering faces today. You will not learn UML or SysML. Executable models are introduced in the case studies, but again with little depth. Domain-specific modeling versus generic modeling (with say UML) is a hot topic not covered in the text. The advantages and disadvantages of auto-generated software are also not covered. Problems of integrating the model-based paradigm with legacy sysems is also missing. Pattern-based architectural development is also not covered. The case studies themselves specifically address classroom exercises with assignments and intructor responses, so depth seems intended to be obtained beyond the text through instructor interaction and hands on development. Each chapter could be expanded into an entire book.
What would I recommend as a more bit more practical introduction to model-driven systems engineering which addresses an audience both inside and outside the university classroom? Your favorite book on UML, A Practial Guide to SysML by Friedenthal, Moore and Steiner, and Systems Engineering with SysML/UML by Weilkiens. The Friedenthal et al. book has an introductory section which motivates the model-based systems engineering paradigm. I'd also recommend software architecture books, Documenting Software Architectures 2nd ed by Clements, Bachman, Bass and Garlan and Software Architecture: Foundations, Theory, and Practice by Taylor, Medvidovic and Dashofy (a bit more theoretical and not particularly model-based).
Don't be surprised if you see my copy available soon on Amazon Marketplace. I guarantee that it is in like new condition :)Architecture and Principles of Systems Engineering (CRC Complex and Enterprise Systems Engineering) OverviewThe rapid evolution of technical capabilities in the systems engineering (SE) community requires constant clarification of how to answer the following questions: What is Systems Architecture? How does it relate to Systems Engineering? What is the role of a Systems Architect? How should Systems Architecture be practiced?A perpetual reassessment of concepts and practices is taking place across various systems disciplines at every level in the SE community. Architecture and Principles of Systems Engineering addresses these integral issues and prepares you for changes that will be occurring for years to come. With their simplified discussion of SE, the authors avoid an overly broad analysis of concepts and terminology. Applying their substantial experience in the academic, government, and commercial R&D sectors, this book is organized into detailed sections on: Foundations of Architecture and Systems EngineeringModeling Languages, Frameworks, and Graphical ToolsUsing Architecture Models in Systems Analysis and DesignAerospace and Defense Systems EngineeringDescribing ways to improve methods of reasoning and thinking about architecture and systems, the text integrates concepts, standards, and terminologies that embody emerging model-based approaches but remain rooted in the long-standing practices of engineering, science, and mathematics. With an emphasis on maintaining conceptual integrity in system design, this text describes succinct practical approaches that can be applied to the vast array of issues that readers must resolve on a regular basis. An exploration of the important questions above, this book presents the authors' invaluable experience and insights regarding the path to the future, based on what they have seen work through the power of model-based approaches to architecture and systems engineering.
