OData is a web protocol that unlocks data silos to facilitate data access from browsers, desktop applications, mobile apps, cloud services, and other scenarios. In this screencast, you'll see how easy it is to set up on OData service (deployed on Windows Azure) for an IBM DB2 database (running on IBM's cloud service), with examples of how to use the service from browsers, client apps, phone apps, and Microsoft Excel.
Here's an overview of the screencast, with links to specific sections:
