11.2 Expanding Web Application with Web Services

Over the past decade or so, the web has been embraced by millions of businesses as an inexpensive
channel to exchange a few words and exchange information with forecast and transactions with
clientele.
In particular, the web provides a way for marketers to get to know the public visiting their
sites and create communicating with them. One way of doing this is asking Web Company to
subscribe to newsletters, to submit an application form when requesting information on products
or provide details to customize their browsing experience when next visiting a particular website.
The web is also an excellent sales channel for a myriad of organizations, large or small: with
over 1 billion Internet users today. All this data must be somehow captured, stored, processed
and transmitted to be used immediately or at a later date. Web applications, in the form of
submit fields, enquiry and login forms, shopping carts, and content management systems, are
those website widgets that allow this to happen.
They are, therefore, fundamental to businesses for leveraging their online presence thus creating
long-lasting and profitable relationships with prospects and customers.
No wonder web applications have become such a ubiquitous phenomenon. However, due to
their highly technical and complex nature, web applications are a widely unknown and a grossly
misunderstood fixture in our everyday cyber-life.
11.2.1 Web Applications Defined

From a technical view-point, the web is a highly programmable environment that allows mass
customization through the immediate deployment of a large and diverse range of applications,
to millions of global users. Two important components of a modern website are flexible web
browsers and web applications; both available to all and sundry at no expense.
Web browsers are software applications that allow users to retrieve data and interact with
content located on web pages within a website.
Today’s websites are a far cry from the static text and graphics showcases of the early and
mid-nineties: Modern web pages allow personalized dynamic content to be pulled down by
users according to individual preferences and settings. Furthermore, web pages may also run
client-side scripts that “change” the Internet browser into an interface for such applications as
web mail and interactive mapping software (e.g., Yahoo Mail and Google Maps).

Most importantly, modern web sites allow the capture, processing, storage and transmission of
sensitive customer data (e.g., personal details, credit card numbers, social security information,
etc.) for immediate and recurrent use. And, this is done through web applications. Such features
as webmail, login pages, support and product request forms, shopping carts and content
management systems, shape modern websites and provide businesses with the means necessary to
communicate with prospects and customers. These are all common examples of web applications.
