A Practical Comparison of ADO and ADO.NET

Since "classic" ASP's humble beginnings, ADO data access classes and methods have been re-written to form ADO.NET. In this article Joe looks at the differences (in terms of classes, methods, and calling conventions) that exist between ADO and ADO.NET. He provides several practical examples that show us how to evolve from using ADO with ASP to using ADO.NET with C# and ASP.NET.

A Practical Comparison of ADO and ADO.NET - Conclusion
(Page 7 of 7 )

In this article we've taken a detailed, comparative look at ADO and ADO.NET. We've seen how it's possible to accomplish one thing in ADO, and then how we can accomplish that exact same thing with ADO.NET. If you're currently working with ASP/VB and ADO, then hopefully this article has given you some incentive to take a look at ADO.NET in further detail. If you're already using ADO.NET, then hopefully this article has cleared up any unsureness that you have.

As you begin to learn more about ADO.NET, it will become more obvious that its underlying data is represented internally as XML, and this makes for a big change in terms of interoperability and speed. If you'd like to learn more about ADO.NET, you can purchase one of the books shown below.
