Murach's Visual Basic 2005
How to use data sources with business objects

This chapter shows you how to do database processing using object data sources, which are data sources that get their data from business objects. This lets you get the benefits of data binding that are provided by data sources, while keeping the data access code and business objects in a layer separate from the presentation code so that you can create true multi-layer applications.
