This entertaining and often enlightening text defines what seasoned developers have long suspected: despite advances in software engineering, most software projects still fail to meet expectations — and about a third are cancelled altogether. The authors of AntiPatterns draw on extensive industry experience, their own and others, to help define what’s wrong with software development today. They outline reasons why problem patterns develop (such as sloth, avarice, and greed) and proceed to outline several dozen patterns that can give you headaches or worse. Their deadliest hit list begins with the Blob, where one object does most of the work in a project, and Continuous Obsolescence, where technology changes so quickly that developers can't keep up. Some of the more entertaining antipatterns include the Poltergeist (where do-nothing classes add unnecessary overhead), the Boat Anchor (a white elephant piece of hardware or software bought at great cost) and the Golden Hammer (a single technology that is used for every conceivable programming problem). The authors then proceed to define antipatterns oriented toward management problems with software (including Death by Planning and Project Mismanagement, along with several miniature antipatterns, that help define why so many software projects are late and overbudget). The authors use several big vendors' technologies as examples of today’s antipatterns. Luckily, they suggest ways to overcome antipatterns and improve software productivity in “refactored solutions” that can overcome some of these obstacles. However, this is a realistic book, a mix of “Dilbert” and software engineering. A clever antidote to getting too optimistic about software development, AntiPatterns should be required reading for any manager facing a large-scale development project.

Alistair Cockburn’s Writing Effective Use Cases is an approachable, informative, and very intelligent treatment of an essential topic of software design.Показать полностьюAlistair Cockburn’s Writing Effective Use Cases is an approachable, informative, and very intelligent treatment of an essential topic of software design. “Use cases” describe how “actors” interact with computer systems and are essential to software-modeling requirements. For anyone who designs software, this title offers some real insight into writing use cases that are clear and correct and lead to better and less costly software. The focus of this text is on use cases that are written, as opposed to modeled in UML. This book may change your mind about the advantages of writing step-by-step descriptions of the way users (or actors) interact with systems. Besides being an exceptionally clear writer, the author has plenty to say about what works and what doesn't when it comes to creating use cases. There are several standout bits of expertise on display here, including excellent techniques for finding the right “scope” for use cases. (The book uses a color scheme in which blue indicates a sea-level use case that’s just right, while higher-level use cases are white, and overly detailed ones are indigo. Cockburn also provides notational symbols to document these levels of detail within a design.) This book contains numerous tips on the writing style for use cases and plenty of practical advice for managing projects that require a large number of use cases. One particular strength lies in the numerous actual use cases (many with impressive detail) that are borrowed from real-world projects, and demonstrate both good and bad practices. Even though the author expresses a preference for the format of use cases, he presents a variety of styles, including UML graphical versions. The explanation of how use cases fit into the rest of the software engineering process is especially good. The book concludes with several dozen concrete tips for writing better use cases. Software engineering books often get bogged down in theory. Not so in Writing Effective Use Cases, a slender volume with a practical focus, a concise presentation style, and something truly valuable to say. This book will benefit most anyone who designs software for a living.

Based on real world problems and systems, this book takes a practical approach to architectural solutions, giving step-by-step advice on how to design high performance, controllable and flexible systems.

As the application of object technology — particularly the Java programming language — has become commonplace, a new problem has emerged to confront the software development community.Показать полностьюAs the application of object technology — particularly the Java programming language — has become commonplace, a new problem has emerged to confront the software development community. Significant numbers of poorly designed programs have been created by less-experienced developers, resulting in applications that are inefficient and hard to maintain and extend. Increasingly, software system professionals are discovering just how difficult it is to work with these inherited, "non-optimal" applications. For several years, expert-level object programmers have employed a growing collection of techniques to improve the structural integrity and performance of such existing software programs. Referred to as "refactoring," these practices have remained in the domain of experts because no attempt has been made to transcribe the lore into a form that all developers could use. . .until now. In Refactoring: Improving the Design of Existing Code, renowned object technology mentor Martin Fowler breaks new ground, demystifying these master practices and demonstrating how software practitioners can realize the significant benefits of this new process. With proper training a skilled system designer can take a bad design and rework it into well-designed, robust code. In this book, Martin Fowler shows you where opportunities for refactoring typically can be found, and how to go about reworking a bad design into a good one. Each refactoring step is simple — seemingly too simple to be worth doing. Refactoring may involve moving a field from one class to another, or pulling some code out of a method to turn it into its own method, or even pushing some code up or down a hierarchy. While these individual steps may seem elementary, the cumulative effect of such small changes can radically improve the design. Refactoring is a proven way to prevent software decay. In addition to discussing the various techniques of refactoring, the author provides a detailed catalog of more than seventy proven refactorings with helpful pointers that teach you when to apply them; step-by-step instructions for applying each refactoring; and an example illustrating how the refactoring works. The illustrative examples are written in Java, but the ideas are applicable to any object-oriented programming language.

Design Patterns is a modern classic in the literature of object-oriented development, offering timeless and elegant solutions to common problems in software design.Показать полностьюDesign Patterns is a modern classic in the literature of object-oriented development, offering timeless and elegant solutions to common problems in software design. It describes patterns for managing object creation, composing objects into larger structures, and coordinating control flow between objects. The book provides numerous examples where using composition rather than inheritance can improve the reusability and flexibility of code. Note, though, that it’s not a tutorial but a catalog that you can use to find an object-oriented design pattern that’s appropriate for the needs of your particular application — a selection for virtuoso programmers who appreciate (or require) consistent, well-engineered object-oriented designs.

The architects of the Software Factories method provide a detailed look at this faster, less expensive, and more reliable approach to application development.Показать полностьюThe architects of the Software Factories method provide a detailed look at this faster, less expensive, and more reliable approach to application development. Software Factories significantly increase the level of automation in application development at medium to large companies, applying the time tested pattern of using visual languages to enable rapid assembly and configuration of framework based components.Unlike other approaches to Model Driven Development (MDD), such as Model Driven Architecture (MDA) from the Object Management Group (OMG), Software Factories do not use the Unified Modeling Language (UML), a general purpose modeling language designed for models used as documentation. They go beyond models as documentation, using models based on highly tuned Domain Specific Languages (DSLs) and the Extensible Markup Language (XML) as source artifacts, to capture life cycle metadata, and to support high fidelity model transformation, code generation and other forms of automation.

This book is based on Objectory which is the first commercially available comprehensive object-oriented process for developing large-scale industrial systems. Ivar Jacobson developed Objectory as a result of 20 years of experience building real software-based products. The approach takes a global view of system development and focuses on minimizing the systems life cycle cost. Objectory is an extensible industrial process that provides a method for building large industrial systems. This revised printing has been completely updated to make it as accessible and complete as possible. New material includes the revised Testing chapter, in which new product developments are discussed.

Aspect-oriented programming (AOP) is a revolutionary new way to think about software engineering. AOP was introduced to address crosscutting concerns such as security, logging, persistence, debugging, tracing, distribution, performance monitoring, and exception handling in a more effective manner.Показать полностьюAspect-oriented programming (AOP) is a revolutionary new way to think about software engineering. AOP was introduced to address crosscutting concerns such as security, logging, persistence, debugging, tracing, distribution, performance monitoring, and exception handling in a more effective manner. Unlike conventional development techniques, which scatter the implementation of each concern into multiple classes, aspect-oriented programming localizes them. Aspect-oriented software development (AOSD) uses this approach to create a better modularity for functional and nonfunctional requirements, platform specifics, and more, allowing you to build more understandable systems that are easier to configure and extend to meet the evolving needs of stakeholders. In this highly anticipated new book, Ivar Jacobson and Pan-Wei Ng demonstrate how to apply use casesa mature and systematic approach to focusing on stakeholder concernsand aspect-orientation in building robust and extensible systems. Throughout the book, the authors employ a single, real-world example of a hotel management information system to make the described theories and practices concrete and understandable. The authors show how to identify, design, implement, test, and refactor use-case modules, as well as extend them. They also demonstrate how to design use-case modules with the Unified Modeling Language (UML)emphasizing enhancements made in UML 2.0and how to achieve use-case modularity using aspect technologies, notably AspectJ.

This book guides you through meeting that challenge. This unique book gives you more than just a guide to the Moodle software; it uses Moodle as a route to better teaching, more motivated students, and more successful courses. Moodle is the leading Open Source learning management system. Using Moodle, teachers can easily construct richly textured web based courses. A course can consist of a number of lessons, with each lesson including reading materials; activities such as quizzes, tests, surveys, and projects; and social elements that encourage interaction and group work between students.Moodle E-Learning Course Development shows you how to use Moodle as a tool to enhance your teaching. It will help you analyse your students' requirements, and come to an understanding of what Moodle can do for them. After that you'll see how to use every feature of Moodle to meet your course goals. The social constructionist learning philosophy is at the heart of Moodle: we all “construct” knowledge through interation with one another and with learning materials in a social way. Moodle E-Learning Course Develelopment will show you how to add static learning material, interactive activities, and social features to your courses so that students reach their learning potential. Whether you want to support traditional class teaching or lecturing, or provide complete online and distance learning courses, this book will prove a powerful resource throughout your use of Moodle. - Understand what Moodle can do, how it compares to other e-learning packages, and how it can support your teaching strategies — Install the Moodle software on your own computer or a server, and understand your way around it — Know how to create different kinds of courses. Moodle can support courses where the group works through the classes with a shared schedule, or where individual students work through at their own pace, or courses where students are free to explore the different topics in their own time. This book will show you how. - Understand all of Moodle’s learning features. Moodle provides features for managing course content, interactive resources, and social activities such as forums and wikis. This book explains what each of these features are, how they work, and most importantly how and when to use them effectively. - Manage students — so that you can ensure that the right students are going to the right classes; allow students to enrol themselves, or invite students to join a course. You can even set up commercial courses where students pay to sign William Rice is an experienced trainer and expert on learning and teaching practices. This experience and expertise forms the foundation of his approach: What do we want to teach? How would this best translate into a course? How best can Moodle support these course objectives?Of course, the book contains everything you'd expect from an introduction to Moodle: clear step-by-step instructions, plenty of screenshots, explanations and guides through the many features and options that you have to choose from. Throughout the book, William develops an example course. He uses this example to explore the sort of decisions, design considerations, and thought that goes into developing a successful course. This book is written for everyone who wants to get the most from Moodle. Beginners to the software will get a thorough guide to how the software works, and some great ideas for getting to a good start with their first course. More experienced Moodlers will find powerful insights into developing more successful and educational courses.
