Murach's ASP.NET 3.5 with VB 2008
How to use object data sources

This chapter shows you how to use object data sources to implement 3-layer applications in which the data access code is kept in data access classes. Unlike the Access and SQL data sources that are covered earlier in the book, object data sources let you separate the the data access code from the presentation code, but still let you use the data binding features of ASP.NET 3.5.
