Experiences in engineering flexible Web services

ACM SIGSOFT Software Engineering Notes, 2001

The series of workshops on Web Engineering started in 1998 with the World Wide Web Conference WWW7 in Brisbane, Australia, and has continued with WWW8 (Toronto, 1999) and WWW9 (Amsterdam, 2000). The first such workshop with the International Conference on Software Engineering (ICSE) took place in 1999 in Los Angeles. The second workshop was held on 4-5 June 2000 in Limerick, Ireland and attracted about 30 participants.The main purpose behind these workshops is to share and pool the collective experience of people, both academics and practitioners, who are actively working on Web-based systems.This workshop consisted of two keynote addresses, 11 contributed papers and two sessions of open discussions. The call for papers elicited 18 submissions of which 11 were accepted after peer reviews. The papers presented at the workshop appear in the book Web Engineering (San Murugesan and Yogesh Deshpande (eds.), LNCS, Springer-Verlag, 2000).

Web engineering, an emerging new discipline, advocates a process and a systematic approach to development of high quality Web based systems. In contrast the commercial practice still remains ad-hoc. Although the Web based systems has become increasingly complex, the development process is still un-engineered. "There are very few standard methods for the Web developers to use. Hence, there is a strong need to understand and undertake Web engineering ". (Y. Deshpande and M. Gaedke, 2005) This paper is a result of our extensive survey of literature, our work and interaction with developers. This paper gives an introductory overview on Web engineering, it assesses similarities and differences between development of traditional software and Web based systems, and reviews some of the ongoing work in this area. We discuss the need for development of process model for Web based applications (WBA). such as is available far conventional software, with an overview of our work on development of such a process framework (R. Ahmad, et al, 2005). This paper also attempts to highlight the areas that need further study.

Web Engineering, an emerging new discipline, advocates a process and a systematic approach to development of high quality Web-based systems or applications. It promotes the establishment and use of sound scientific, engineering and management principles, and disciplined and systematic approaches to development, deployment and maintenance of Web-based systems [1]. Earlier Web-developers regarded Web Engineering as a specialized field of Software Engineering but it comprises more than it because every web application comprises content, hypertext structure and presentation for a possibly very divertive audience, web developers must supply a broad variety of domain knowledge. As Powel [2] writes Web-based systems ―involve a mixture between print publishing and software development, between marketing and computing, between internal communications and external relations, and between art and technology.‖In view of the nature of the Web and Web-based applications, Web engineering is bound t...

In most cases, development of Web-based systems has been ad hoc, lacking systematic approach and quality control and assurance procedures. Hence, there is now legitimate and growing concern about the manner in which Web-based systems are developed and their long-term quality and integrity. Web Engineering, an emerging new discipline, advocates a process and a systematic approach to development of high quality Web-based systems. It promotes the establishment and use of sound scientific, engineering and management principles, and disciplined and systematic approaches to development, deployment and maintenance of Web-based systems. This paper gives an introductory overview on Web Engineering. It presents the principles and roles of Web Engineering, assesses the similarities and differences between development of traditional software and Web-based systems, identifies key Web engineering activities and reviews some of the ongoing work in this area. It also highlights the prospects of Web engineering and the areas that need further study.

The paper gives an overview of the new features of web technologies. The general idea of the new version of HTML (Hyper Text Markup Language), i.e. HTML5, and other tools presented in this paper is the formal specification and the establishment of uniform solutions for technologies and functionalities which have already been in use through various hacks and plug-ins proposed by web developers. Many of these functionalities will now be implemented in browsers. The applications can access these functionalities through newly defined application programming interfaces. The latter include support for multimedia, dynamic graphic rendering, geolocation, multithreading, local data storage etc. HTML5 also introduces semantic markup, which can be used for marking the document structure as well as its elements and data. The new version of HTML enforces strict separation of the page content from its style. The styling can only be done using CSS (Cascading Style Sheets) language. The new CSS version, i.e. CSS3, has a modular structure, in which different modules define different styling features. The development cycles of the individual modules are independent as well as their support and implementation in various browsers.

Web-based systems and applications now deliver a complex array of functionality to a large number of diverse groups of users. As our dependence and reliance on the Web has increased dramatically over the years, their performance, reliability and quality have become paramount importance. As a result, the development of Web applications has become more complex and challenging than most of us think. In many ways, it is also different and more complex than traditional software development. But, currently, the development and maintenance of most Web applications is chaotic and far from satisfactory. To successfully build and maintain large, complex Web-based systems and applications, Web developers need to adopt a disciplined development process and a sound methodology. The emerging discipline of Web engineering advocates a holistic, disciplined approach to successful Web development. In this chapter, we articulate and raise awareness of the issues and considerations in large, complex Web application development, and introduce Web engineering as a way of managing complexity and diversity of large-scale Web development.

Abstract According to (C.Alexander,S.Ishikawa,M,Silverstein,M.Jacobsen,M.Fiksdahl-king,S.Angel, 1997) a pattern describes a problem which occurs over and over again in our environment and then describes the core of the solution to that problem. Therefore we say that design patterns are reusable elements of software. Their common level of abstraction is a component that solves a general design problem in a particular context, but does not span an entire application or subsystem (Gamma et al, 1994). You need to note that a design pattern is not a finished design that can be transformed directly into code. It is a description or template for how to solve a problem that can be used in many different situations. Therefore when we say that algorithms are not thought of as design patterns we are not wrong, this is because they solve computational problems rather than design problems. This research paper will shed more light on the functions of web application design patterns. Web design Patterns applications have become popular since it promotes among others reusability, security and consistency. The main objective of this paper is to show the role design patterns play in web application design.
