Most data-driven web applications have a fixed data model and user interface. What I mean by “fixed” it that the data it needs to be captured is known in advance.

Such applications are more difficult to create because both the data model and user interface need to be flexible enough to allow the user to specify the information to be captured

There’s no need to write any source code; the data source controls allow declarative access to data. For more information on working with data in ASP.NET see my Accessing and Updating Data in ASP.NET article series and Working with Data tutorials.
