About This Episode

In this episode, Keith and Woody sit down at PDC 2009 with Microsoft’s Douglas Purdy to discuss all things data. Do you remember Oslo from the previous PDC event? Well Oslo has been rebranded to SQL Server Modeling to help developers store and manage models for the enterprise. SQL Modeling enables you to more productive when building and managing data-driven applications. The guys also get the low down from Douglas on a new web protocol for querying and updating data called OData.

Thanks to our guests this episode

This is great! Thank you, there must be not enough simple implementations of OData with WCF Data Services out there. This really helped me out and gave me a good starting place to play around with WCF Data Services without EDM.

This podcast was truly enlightening to understand the SQL Server Modeling which is the new name for what we called Oslo!! It is really going to help developers like us save a lot of time and effort because it helps to store and manage models for enterprise!! Microsoft’s Douglas Purdy sure knows what he is talking about and has done a wonderful job of explaining about what the web protocol for querying and updating data called OData is all about!!

OData services are straightforward to deploy manually, from your development environment to your test or production environment, with two high-level steps: deploy the database and deploy the web application files.

The MODEL clause brings a new level of power and flexibility to SQL calculations.

When using Spatial Model, a gap appears in the flow of service as the OData spatial types are not cross compatible with the SQL Spatial library.
