Sams Teach Yourself ADO.NET in 24 Hours

Summary

In this hour, you've seen an introduction to tiered development methodologies using ASP.NET and ADO.NET. First, you saw how to implement an additional application layer using a simple SqlDataReader example to display a list of products. Then, you saw how to return a custom class with database values, rather than using a single-row DataTable. In the next hour, you'll see how to handle an application's database modifications using three-tier development practices.
