SQL Data Services going relational

Microsoft announced today that SDS are getting relational features and dropping the ACE (Authority, Container, Entity) features. It will still be possible to use HTTP/REST to access relation datá through ADO.NET data services. I think this is good news, I wasn’t all that comfortable with the ACE concept as a replacement for SQL. So much of current programs, services and products rely on SQL and it would be hard to port them to Azure and ACE. Porting for Azure and SDS with SQL will be much easier and probably speed adoption.
