Business Component Factory : A Comprehensive Overview of Component-Based Development for the Enterprise ReviewThis book is the first I have read that really tackles all aspects of what is required for Enterprise Application Development through a CBD approach.
By defining the levels of component granularity and a recursively discrete approach to breaking a business problem down into components and their constituents as finer grained components, the true requirements for CBD are evident and determined. Many books I have read make the same mistake of only discussing development of components at one level (usually what Herzum defines as the distributed component level) and fail to address the many of the aspects of CBD that are not covered by development alone (deployment, testing, management, integration, and a roadmap for the development process and managment of that process through to delivery of a component based system). The book also talks and applies the component levels to the commonly depicted 4 tier architecture and importantly introduces the concept of components needing to be not only strongly typed for internal systems but also strongly tagged (supporting XML based component messaging/invocation) for virtual and extended systems. The coverage of what is required from a Component Execution Environment (CEE) when components are more course grained than simple distributed components is well covered and continues to define the true requirements for a Business Component Execution Environment (BCVM).
The book is a must read for anyone serious about adopting CBD on and enterprise scale. The book goes well beyond the common text available for CBD (that all concentrate on the short sighted development requirements for distributed components in a fine grained component containment model). I agree with another reviewer that for those of us that have been developing systems in EJB, COM+/DCOM and CORBA much of the book covers lessons we have painfully had to learn in developing multiple component based systems that have to inter-operate, but it goes beyond that in looking at what is necessary for component based systems at the next architectural level (one that may well incorporate disparate distributed component models).Business Component Factory : A Comprehensive Overview of Component-Based Development for the Enterprise OverviewIn this book, Peter Herzum and Oliver Sims present a complete component based strategy, the business component approach, that applies and extends component thinking to all aspects of the software life cycle for enterprise systems. The approach includes a conceptual framework that brings components into the world of scalable systems, and outlines the different component granularities.It also includes a methodology that goes beyond current object-oriented practices to provide the concepts required to meet the real challenges of component-based development. Using their business component approach, the authors then provide a blueprint for a business component factory--a development capability that can produce software with the quality, speed, and flexibility needed to match changing business needs. Sprinkled with guidelines, tips, and architectural patterns, this book fully prepares you for the approaching component revolution.Praise for Business Component Factory". . . this book should be very useful for anyone considering the daunting task of adopting component software on an enterprise scale."-Clemens Szyperski (Microsoft Research), Author of the award-winning book, Component Software: Beyond Object-Oriented Programming"Herzum and Sims do an admirable job of differentiating the different component concepts, allowing this clearly written book to focus on the construction of business systems by non-software practitioners, out of business component parts developed separately (and perhaps for a commodity component marketplace). This is the future of software systems, and this book is a practical, giant step in that direction."-Richard Mark Soley, PhD,Chairman and CEO, OMG"Finally, a book that takes you from component design all the way down to the middleware on which they are deployed. It?s an important contribution to the nascent server-side component discipline written by practitioners for practitioners."-Robert Orfali, Author of Client/Server Survival Guide, Third Edition and Client/Server Programming with Java and CORBA, Second Edition (both from Wiley)

Practical Common Lisp ReviewI've been recommending this text to people who want to start learning Common Lisp since it was first available in draft form on the author's web site. Now that it's out in print I can enthusiastically recommend that anybody who is interested in learning Common Lisp - or even curious about how the language can improve your productivity - purchase it.
Peter has a very enjoyable and easy-to-understand writing style, and he starts early with practical examples that show how Common Lisp can be used to solved problems. Chapter 3, "A Simple Database", is a great explanation of how programs are grown from pieces in Common Lisp to solve large problems. It's presented early and draws people in to the problem solving techniques used when programming in Lisp.
Peter doesn't skimp on details, though: detailed chapters on FORMAT (for formatted output), LOOP (for general iteration / value collection), and CLOS (the Common Lisp Object System) provide a wonderful tutorial to these powerful but complex features.
The book ends with a long string of practical examples that synthesize multiple concepts into programs that are useful and show exactly why programming in Lisp is so cool. The last practical example, which builds a HTML generation library in Lisp, gives the reader a taste of why writing a Domain-Specific Language is so easy in Lisp and why it can integrate so well with the rest of the language.
Peter is very enthusiastic about Common Lisp and it shows in his writing. Unlike other authors (Paul Graham comes to mind) he gives every major feature of the language its due and shows how and where it should be used.
Practical Common Lisp may be one of the most fun books on programming you'll read all year. Even if you're just curious, check it out. It may change the way you program.Practical Common Lisp Overview...it has a fresh view on the language and the examples in the later chapters are usable in your day-to-day work as a programmer. — Frank Buss, Lisp Programmer and Slashdot ContributorIf you're interested in Lisp as it relates to Python or Perl, and want to learn through doing rather than watching, Practical Common Lisp is an excellent entry point. — Chris McAvoy, Chicago Python Users Group Lisp is often thought of as an academic language, but it need not be. This is the first book that introduces Lisp as a language for the real world.
Practical Common Lisp presents a thorough introduction to Common Lisp, providing you with an overall understanding of the language features and how they work. Over a third of the book is devoted to practical examples such as the core of a spam filter and a web application for browsing MP3s and streaming them via the Shoutcast protocol to any standard MP3 client software (e.g., iTunes, XMMS, or WinAmp). In other "practical" chapters, author Peter Seibel demonstrates how to build a simple but flexible in-memory database, how to parse binary files, and how to build a unit test framework in 26 lines of code.

Structured Systems Analysis: Tools and Techniques. (Prentice-Hall software series) ReviewAs a business process consultant and information systems designer, I am constantly looking for effective techniques for capturing business details and new system requirements. I have looked at every new tool and method to come along, but this is STILL the best one there is. A testament to this book and it's methods is that many of the latest software tools, using the latest technology, still build on the methods and diagrams used in this book. And it's all still valid. Every consultant, business analyst, and systems designer MUST have a copy of this book in their library!Structured Systems Analysis: Tools and Techniques. (Prentice-Hall software series) OverviewThis valuable volume provides a practical technique for building a logical (non-physical) model of a commercial data processing system. It is extensively illustrated to provide graphic explanations of how systems fit together.
