Software Engineering (7th Edition) ReviewSoftware engineering is to computer science what engineering is to physics, as the author suggests. Here, the emphasis is on a higher level than, say, the crafting of algorithms. The scope is for systems analysis, design and implementation. He explains that the traditional waterfall method had many shortcomings. Its monolithic stages often proved unwieldy.The book goes into alternatives. It also gives a good overall treatment of such ideas as formal specification and architectural design. With an entire chapter focusing on the key ways to have distributed systems architectures. Unsurprisingly, CORBA gets the most extensive description. A reflection of the amount of effort that has gone into using it since the late 80s. However, there is scant mention of its drawbacks. Most important of which has been that the exchange of binary data has been very brittle.
He mentions p2p and Web Services, as contrasting approaches. Where the latter uses XML to exchange data in a readable format. This has been widely seen as a big advantage over CORBA, but the book doesn't mention it. Given the continued rise in Web Services, perhaps a future edition of the book could give it more coverage?
The most controversial part of the text might be the section on Extreme Programming. Its characteristics are well described. But perhaps not enough on its disadvantages. Like the idea of collective ownership of code. Not all programmers have the same ability or expertise. Some programmers are far better than others. It is very bad to have a tyro unwittingly change code for which she has insufficient understanding. While the author may not necessarily agree with this, he should at least describe it.
Other sections of the book, especially on testing software and validating critical system parts, are quite lucid and should excite little disagreement.Software Engineering (7th Edition) OverviewSoftware Engineering presents a broad perspective on software systems engineering, concentrating on widely used techniques for developing large-scale systems. The objectives of this seventh edition are to include new material on iterative software development, component-based software engineering and system architectures, to emphasize that system dependability is not an add-on but should be considered at all stages of the software process, and not to increase the size of the book significantly.To this end the book has been restructured into 6 parts, removing the separate section on evolution as the distinction between development and evolution can be seen as artificial. New chapters have been added on:Socio-technical Systems discussing the context of software in a broader system composed of other hardware and software, people, organisations, policies, procedures and laws.Application System Architectures to teach students the general structure of application systems such as transaction systems, information systems and embedded control systems. The chapter covers 6 common system architectures with an architectural overview and discussion of the characteristics of these types of system.Iterative Software Development looking at prototyping and adding new material on agile methods and extreme programming.Component-based Software Engineering introducing the notion of a component, component composition and component frameworks and covering design with reuse.Software Evolution revising the presentation of the 6th edition to cover re-engineering and software change in a single chapter.The book supports students taking undergraduate or graduate courses in software engineering, and software engineers in industry needing to update their knowledge.
