This chapter is your complete reference to the database—to client objects that are part of the ADO .NET class library. As you can clearly see, ADO .NET provides you with a very powerful set of objects used to communicate with databases. If you want a completely practical tutorial of how to interact with databases in ADO .NET, read Chapter 7.
The next chapter is also a theoretical reference to the objects within ADO .NET that allow you, the developer, to take control of data manipulation in your client application.
