[This article was contributed by the SQL Azure team.]
One of the reasons that SQL Azure is such a powerful tool is that it's based on the same database engine as SQL Server. For example, you can connect to the Microsoft SQL Azure Database with the sqlcmd command prompt utility that is included with SQL Server.
