Abstract
In
recent years the Internet and mostly the World Wide Web (WWW) passed through
large growth. The Internet has become generally used, so it affected the
development of applications. A kind of applications appeared where a browser
takes care of showing the user interface. These applications are known as 'web
application'.
A web application is typically based on client/server architecture. The
client is a browser, which communicates with a web server. Data sent to the
client can change continuously, so we need server-side components can produce
HTML pages dynamically based on the contents of the underlying database.
In my presentation I would like to present the Digitalcity portal
(www.digitalcity.hu). It makes possible to appear on the Internet for everyone
including those who don’t have possibility to maintain their own web site.
After the registration process our clients can edit their pages themselves.
They need only a browser to achieve it, because the application contains an
editor. The constructed pages fit into the portal’s structure.
In my presentation concepts appearing in Digitalcity will be explained.
The infrastructure and the development tools will be described as well. Then
the applied technologies, mainly server-side Java technologies and Net.Data
macro language, and its advantages and disadvantages will be discussed as well
as the underlying database management system. Finally the process of how this
web application has been built by the integration of these technologies will be
shown.
