Web Applications

Web applications consist of technologies that can create dynamic and interactive tools out of static, inactive web sites. For this, popular internet technologies are used to build an application, which is hence available for all users of the internet or intranet.

A web application is a so-called client/server application. Whereas the application itself is run centrally on one or more servers, the client is responsible for the display of the application in the browser. Through input boxes, buttons or links the user communicates with the application on the server. So a bi-directional communication is established and the user can operate the server application.

The spectrum of functions can reach from a plain personalization of the shown contents to applications which appear like programs installed on the local computer. The spatial separation of applications and user interface in combination with the internet guarantees easy access for end users and minimal installation efforts on the terminal. Central storage of functionality and data provides easy maintenance as well as easy and focused safeguarding against third-party influence and makes it easy to provide redundant systems. Integration of data or functionality to other systems is simplified.

Development of a Web Application

The development of a web application consists of several steps:

  • planning
  • design of a prototype
  • implementation of the application

Planning together with the customer has top priority. Wishes and requirements of the customer are determined in precise agreements, functionality is developed and available technical resources for realization are clarified.

The next step consists of the design of a prototype. This helps to clear questions concerning design, click-flows, page layout etc. with the customer. Mostly the prototype is called upon as basis for the implementation of the application.

On implementation the basic requirements of the customer should be kept in mind. Such requirements can be:

  • platform independence
  • multi-user-capability
  • processing speed
  • stability etc.
