Understanding Data Sources

Dynamic Web applications require a data source from which they can retrieve and display the latest information on a Web page. In UltraDev, you can decide to use databases, request variables, URL variables, server variables, form variables, or stored procedures as sources of data.

Before you can use any of these data sources for your Web application, you need to define these data sources for every Web page of the Web application. Defining a data source involves specifying the information that must be retrieved from a database. When you want the information to be retrieved from a database, the data source that is defined in UltraDev retrieves this information. This information is then used to add dynamic content to your Web application.
