XII. Querying Data by Using WCF Data Services

Windows Communication Foundation (WCF) Data Services enable you to create highly flexible data services that can be used to provide access to data across the Internet or a corporate network. You can access these services by using REST-style URIs, and they can be easily consumed by a wide variety of applications. As WCF Data Services are build on top of standard Internet protocols such as HTTP and the Atom Publishing Protocol, they are an ideal choice for delivering data to AJAX applications and Rich Interactive Applications built using technologies such as Microsoft Silverlight.

XV. Using LINQ to SQL

ADO.NET provides a mechanism that enables you to build applications that can query and maintain data that is held in a variety of sources in a database-agnostic manner. However, building applications by using ADO.NET requires that you are familiar with the Structured Query Language (SQL) language and features of the database management system that you are connecting to. Language-Integrated Query (LINQ) to SQL provides a higher-level abstraction for managing data that is held in a Microsoft SQL Server database, and is an ideal stepping stone for migrating ADO.NET applications toward the ADO.NET Entity Framework. This module introduces LINQ to SQL and explains how you can use it to abstract the low-level details of ADO.NET queries by developing against a logical data model.
