As you ve seen in this chapter, ADO.NET gives you two ways to solve the same problems. Direct commands are the leanest, most straightforward approach, and they sidestep some of the headaches you ll face with disconnected data. On the other hand, DataSets really shine when you need to work with more than one related table, and they also work well with the data binding techniques you ll use in 14 and 15. Which one you use depends on the situation, but in many cases, both approaches will work equally well. The key fact you should realize is that the simpler approach using direct commands often makes perfect sense. Overeager .NET converts sometimes try to use the DataSet everywhere, needlessly complicating life. But if you re happy with forward-only, read-only data and you don t need to convert your data to XML or send it to another component, there s no embarrassment in using ADO.NET s DataReader.

A code review is more ad hoc. It typically involves printing out some code and examining it for adherence to coding standards, scanning for possible bugs and so on. A code review finishes with an informal list of to-do items, written on a sticky note or in a follow-up e-mail. In a code review, gathering of metrics is less common.

This chapter gave you a comprehensive introduction to ADO.NET and its new disconnected data model. Although you ve seen all the core concepts, you still have much more to learn. For a comprehensive book that focuses exclusively on ADO.NET, you may be interested in a book such as Microsoft ADO.NET 2.0: Core Reference (Microsoft Press, 2005), which investigates some of the techniques you can use to optimize ADO.NET data access code. In the next two chapters, you ll learn about ASP .NET s new data binding features and see how you can use them with a little ADO.NET code to write practical data-driven pages.
