ASP.NET MVC with ADO.NET DataServices

In the project i am working on, i want to use the ADO.NET data services as data access layer. so that other parts of my application (except asp.net mvc web site) could also access it from the same location. I am just not sure if this si the correct model and also for asp.net mvc models I wanted to reuse the data services model, as much as possible and also some how decorate them as required fields etc.

Other option i star开发者_StackOverflow社区ted looking at was to use RIA services as back end to the MVC site.

I am very confued at the moment and any help would be appriceated.

Have you taken a look into WCF data services?
