Murach's ADO.NET 2.0 with VB 2005
How to use object data source controls

This chapter shows you how to use the object data source control as an alternative to the SQL data source control in ASP.NET 2.0 applications. This allows you to create true 3-layer applications in which the data access code is separated from the presentation code, yet still use the data binding features of ASP.NET 2.0.
