Have an upvote, I&#x27;m not sure why you&#x27;re being down-voted.<p>If you take the issues of open-source and licensing out of the equation (both important issues in their own right, but not related to the point at hand) then Oracle and SQL Server are both ridiculously good.<p>I personally try to avoid them (due to the cost, and the lock-in) but they <i>are</i> astoundingly performant and featureful RDBMSs with a huge amount of support and documentation behind them.
