Relevance of design patterns within web applications
Inhaltsangabe:Abstract: In 1994 the Gang of Four, consisting of Erich Gamma, Richard Helm, Ralph Johnson and John Vlissides, published the book Design Pattern - Elements of Reusable Object-Oriented Software. Within that book the four information scientists described 23 design patterns, which they classi?ed into the categories Creational Design Pattern, Structural Design Pattern and Behavioral Design Pattern. Even though design patterns exist since 15 years at present, they have not lost relevance. Due to new concepts the usage of design patterns within web application is increasing. Meanwhile all 23 established design patterns are available as PHP implementations. Aside web languages like AJAX, JavaScript, XHTML and CSS also appreciate the strength of design patterns. At first web languages like AJAX, PHP, et cetera will be analyzed if they qualify for the usage of design patterns. At second the usage of design patterns within open source web applications like Typo3, Joomla, Wordpress, et cetera will be examined. At third various web developers of 1&1, web.de, Telekom, et cetera will be interviewed to investigate if and in which amount design patterns are used by companies. Intention of this thesis is to determine the relevance of design pattern within web applications. Thereby advantages will also be shown like disadvantages. Also the question, if design patterns should be used by default or only if the concerning project reached a specific size, will be answered.

Web Application Design Patterns
Ever notice that—in spite of their pervasiveness—designing web applications is still challenging? While their benefits motivate their creation, there are no well-established guidelines for design. This often results in inconsistent behaviors and appearances, even among web applications created by the same company. Design patterns for web applications, similar in concept to those for web sites and software design, offer an effective solution. In Web Application Design Patterns, Pawan Vora documents design patterns for web applications by not only identifying design solutions for user interaction problems, but also by examining the rationale for their effectiveness, and by presenting how they should be applied. - Design interfaces faster, with a better rationale for the solutions you choose. - Learn from over more than 100 patterns, with extensive annotation on use and extension. - Take a short-cut into understanding the industry with more than 500 full-color screenshots.
Guide to Web Application and Platform Architectures

New concepts and technologies are being introduced continuously for application development in the World-Wide Web. Selecting the right implementation strategies and tools when building a Web application has become a tedious task, requiring in-depth knowledge and significant experience from both software developers and software managers. The mission of this book is to guide the reader through the opaque jungle of Web technologies. Based on their long industrial and academic experience, Stefan Jablonski and his coauthors provide a framework architecture for Web applications which helps choose the best strategy for a given project. The authors classify common technologies and standards like .NET, CORBA, J2EE, DCOM, WSDL and many more with respect to platform, architectural layer, and application package, and guide the reader through a three-phase development process consisting of preparation, design, and technology selection steps. The whole approach is exemplified using a real-world case: the architectural design of an order-entry management system.
