OData (Open Data) Protocol is a Web protocol for querying and updating data from sources such as relational databases, file systems or Web sites. It implements a REST (REpresentational State Transfer) interface and as such provides an easy way for querying data through URL address. WCF Data Services is the Microsoft implementation of OData. This presentation describes these concepts and shows how to create a WCF Data Service to query a database using URL address.
