Book excerpt: ADO.NET and SQL Server 2005

This book excerpt presents the new features for ADO.NET 2.0 and SQL Server 2005. These features include Multiple Active Resultsets, Query Notifications, and User Defined Types.


ADO.NET and System.Xml v. 2.0 -- The Beta Version explains the changes made to these important data programming models in the .NET Framework 2.0. These changes include a Database Schema Discovery API in ADO.NET 2.0 and a plethora of classes for reading, editing, validating and the customizing the serialization of XML documents.

Chapter 5, ADO.NET and SQL Server 2005, describes three areas of functionality in which the two data models share core functionality. The first is MARS, or Multiple Active Results Sets, whish allows more than one results set to be open at one time. The second is SQL Server query notifications, in which the server sends notification of any changes made to source data. The third is SQL Server user-defined types, which allows for the execution of managed code on the Web or application server, the client, and within SQL Server itself.
