 Learn how to create an Internet-addressable WCF service that uses OData to send notifications to SharePoint when the underlying data changes. These notifications are used to trigger events that are attached to external lists.

 This article describes how to create an ASP.NET Windows Communication Foundation (WCF) Data Service to expose the AdventureWorks 2012 LT sample database. This enables you to access the data through the Open Data protocol (OData). When access is established through OData, you can configure a Business Connectivity Services (BCS) external content type that will enable SharePoint to consume the data from the external database. To further enhance this OData source, you can add service contracts to the WCF service that will enable BCS to subscribe to notifications that indicate that the external data has changed.
