How to make a WPF Application access online database?

I am developing a simple WPF Application that requires a database. My question is, can I use an online database to run with my application. That is, can my WPF application access an online database? If yes, then how do I do it? Will the conventional way of accessing the SQL Server work? Also, is there any free online database website available that I can use. I do not need a lot of space. Just need to store 9-10 tables, and about 1开发者_如何学运维5-20 stored procedures.

Take a look at "SQL AZURE". The call it Database as Service: http://msdn.microsoft.com/en-us/sqlserver/dataservices/default.aspx
