ADO.NET is Microsoft's latest data access technology, and, as an integral component of the .NET framework, is far more than simply an upgrade of an existing technology. ADO.NET is a large set of .NET classes that enable us to interact with data sources, manipulate data, and communicate with other applications and Web Services in entirely new ways. This book provides a wealth of information about the ADO.NET. We describe the features and how to use them, as well as providing advice and explanation that will enable you to use ADO.NET effectively. The code examples are concise, and demonstrate how to use a specific techniques rather than how to build entire applications.
