If you use Oracle server, you need a copy of Embarcadero's DB Artisan. It's an amazing product that allows you to change tables, indexes tables, tablespaces without having to learn the arcane syntax and strange table names of Oracle innards. It's a DBA in a box and hugely better than the obtuse GUI that comes with Oracle. Unfortunately I think it runs only under Windoze. Be careful though, it's a powerful tool and can powerfully ruin your production DB in seconds. No affiliation, blah, blah...
