Is SQL Azure a relational database?

Question

I don't really get this. Maybe it's a dumb question.

Is SQL Azure a relational db or it acts just like it?

Using ADO.NET and LINQ I've created a relational or non-relational database?

(I know these questions sound weird......!)

EDIT:

Ok, with one of the answers I've understood an important thing and I can know explain better my question.

i.e.: I've created a non-relational db for my app. Publishing it on Azure and loading on SQL Azure the database will the db be relational or not?

I think it will still be non-relational for the missing of primary keys and foreign keys. Will I get any errors?

So which is the utility of the Table Storage service?

Yes, SQL Azure is a relational database management system. The difference between SQL Azure and traditional MS SQL Server is that SQL Azure is designed to be run with high redundancy (i.e. multiple instances).

Answer 2
