ADO .NET From Square One is designed to get programmers up to speed with ADO.NET fast. It's aimed at developers who have little or no real experience with ADO.NET or .NET in general, and who need to get up to speed with ADO.NET fast. Peter Wright focuses on the issues that will affect developers most when adopting ADO.NET, moving the reader painlessly through everything from simple database access to the manipulation of disjointed XML documents within offline fully relational Datasets. Wright also covers just how to apply ADO.NET to real-world scenarios.ADO .NET From Square One could be considered the ultimate zero-to-hero guide for ADO.NET. It assumes no knowledge of ADO.NET and takes the reader through learning everything there is to know about using ADO.NET in full enterprise applications. Wright starts out exploring the basic structure of ADO.NET, covering the Data provider objects, as well as the critical ADO.NET objects such as the DataTable, and Dataset. He then drills down into great detail on every aspect of ADO.NET, from forward only data access in a web service using a DataReader, to building and navigating a fully relational dataset. Given ADO.N ET's dependence on and support for XML, Wright also explores System.XML, showing where it fits into the ADO.NET puzzle and how to use it both with and outside of ADO.NET.
