Database
When large amounts of data need to be delivered through the Web, a database is implemented. Since most of the information will be presented in the same way, the page should not have to change just the information. A database uses the same display or detail page over and over and simply changes the content based on the input of a form.

A databased Web site requires (1) a Web server to handle the incoming requests of your readers, (2) a database server to hold the information in the database, and usually (3) an application server to handle specific operations. Each of these servers must be allowed to interact and must also speak the same language.

Often these servers are on different computers. This does not mean that a database is impossible. This means that a Web site database is usually a package solution from hosting to back end maintenance. Be aware that not every Web host offers these services.

Examples:
Database- Bands and venues of Gainesville.

TerraServer- A 3 terabytes database of images of the earth's land mass with an image map front end. This database now correlates the selected view with census information, property values, crime rate, level of income for residents, and school information.
