Astoria Online Service –> SQL Server Data Services

April 14th, 2008
Around a year ago in the Mix 2007 conference we announced Project Astoria, an overall initiative to understand how data is used on the web and what frameworks, tools and services could we create to enable new and better applications in this space. Several things resulted from that effort already. One of these results is a unified pattern for ...

IUpdatable & ADO.NET Data Services Framework

April 10th, 2008
Astoria service allows reading/querying of data via the already-established IQueryable interface – this helps in abstracting Astoria from the underlying data source. But there is no existing interface for the update operations (CUD – create, update, delete operations). Hence we came up with IUpdatable interface to support CUD operations ...

Batching Data Service Requests

April 7th, 2008
We have received a fair amount of feedback regarding a number of use cases where it would be beneficial to enable a client of a data service to “batch” up a group of operations and send them to the data service in a single HTTP request.  This reduces the number of roundtrips to the data service for apps that need to make numerous ...

Related entries and feeds: links and link expansion

February 19th, 2008
While going through application scenarios for the ADO.NET Data Services Framework (Project Astoria) one of the first things we noticed is that data-centric applications usually want to bring down graphs of related resources in each interaction with the server. For example, if you are retrieving a resource that represents an "Event", you may ...

AtomPub support in the ADO.NET Data Services Framework

February 14th, 2008
  We have been looking for the last few months at adding first-class support for AtomPub to Project Astoria (we briefly touched on it before here). We are at a point where we have some parts of the AtomPub story and their initial implementation running (and we'll share fresh experimental bits soon), some parts on the design board and ...

Why ADO.NET Data Services Framework (aka Astoria)?

February 4th, 2008
I've responded to a few posts on our online forums asking what the motivations were for building Astoria.  After one of our recent posts to the forums a comment was left that the replies would be a good blog post.  So, what follows is a few of my responses to those forums questions appended together and touched up a bit so they can ...
