What is a web application
A web application is a program, running on the server, that is in control of what you see on the web page. The site you are looking at is controlled by such an application.
Standard websites have static content, which means that all the content you see is stored in exactly that form on the server. If a change is required, the underlying file needs to be modified.
Dynamic websites have a template, which is then filled with changing content. This could be the result of a search, setting a filter on a list of items or taking itīs content from a database, as is the case on this site.
Examples of web applications
- This site is based on database content
- On-line survey
- Any on-line store
- Mailing lists, where you can subscribe and un-subscribe
- Image libraries
- Some on-line photo galleries
