I saw an amazing article on how Oracle would save hundreds of thousands of dollars per year because the tooling was so much better that it took Oracle DBAs 10 seconds less to do a job.

In the appendix to the article it listed the tasks involved. Creating a user using the GUI, creating a table using the GUI..etc

I know a few Oracle DBAs and loads of SQL DBAs and their reaction was one and the same. I don't create users very often, let alone often enough for it to make a blind bit of difference to my cost. What sort of DBA creates tables using the GUI?

Real DBAs script things because their tasks have to be reliable and repeatable across many environments. Ditto rollback activity.
