Categories of Web Applications

Below fig identifies different categories of Web applications depending on their development history and their degree of complexity and gives examples (cf. Murugesan 2000). and(Gerti Kappel)

1. Document Centric (Static homepage,web radio,company web site)
2. Interactive ( Virtual exhibition, news site, travel planning )
3. Transactional ( online banking, shopping, booking system )
4. Workflow based ( E government, B2B solution )
5. Collaborative ( chat room, E learning plateform, P2P-services )
6. Portal oriented ( community portal, online shopping mall, business portal )
7. Ubiquitous (customized services, location aware services, Multi plateform delivery )
8. Semantic ( Knowledge management,syndication, recomender system )
9. Social (web logs, collaborative filtering, Virtual shared workplace )

Definition: Web Engineering

Definition:

Based on this definition and on (Deshpande et al. 2002) we define
Web Engineering as follows:
1) Web Engineering is the application of systematic and quantifiable approaches (concepts, methods, techniques, tools) to cost-effective requirements analysis, design, implementation, testing, operation, and maintenance of high-quality Web applications.
2) Web Engineering is also the scientific discipline concerned with the study of these
approaches.
(Gerti Kappel)

Actually traditional web applications are developed in random order without any systematic approach. One can say that web applications are developed in an ad hoc manner. There are lots of problem in traditional web application. Now to solve the all traditional problems there is a need of engineered development of web applications. So here is the subject web engineering. you can also say that web site engineering.
Now the web applications are developed from the point of view of Software Engineering. In the definition the term analysis,design, implementation, testing, operation, and maintenance are taken from Software Engineering.

Web Engineering (WE) syllabus

Motivation:

The World Wide Web has a massive and permanent influence on our lives. Economy, industry, education, healthcare, public administration, entertainment – there is hardly any part of our daily lives without Web.

Nowadays web is evolving into an application medium. Web applications today are full-fledged, complex software systems providing interactive, and customizable services accessible through different devices; they provide a facility for the realization of user transactions and usually store data in an underlying database.
