These data source controls are server controls
that can be used to bind data to a number of data sources. You now have a more
simplified, powerful, consistent, and extensible approach towards binding data
between your presentation layer controls and a number of data source controls.
You can use these controls to bind data between the data bound controls in your
presentation layer to a variety of data sources seamlessly. You only need to choose
the appropriate data source control that fits your requirement.
These data source controls facilitate a "Declarative programming model and
an automatic data binding behavior". You can use them declaratively in your
presentation layer or programmatically in your source code. The data store that
contains the data and the operations that are performed on this data are abstracted,
and you need not worry about how the data access and data binding logic works
underneath. In essence, the entire ADO.NET Object Model is abstracted using these
data source controls. Further, you can use these data source controls to display both
tabular data as well as hierarchical data in your presentation layer.
Introduction to Data Binding in ASP.NET

In ASP.NET 2.0, you have the following data source controls that are of utmost
importance; these would be discussed in detail later in this chapter:
Object data source control: This control can be used to bind data to middletier
objects to the presentation layer components in an N-tier design.
