it's not that simple

i.e. bugger it up completely? Yep, that's possible, but I hope not!

I've been doing Oracle stuff for ten years now and much of it consists of 
spending great effort to find ways to *avoid* using Oracle, because using 
it is so unpleasant. Using Unix stuff instead is generally vastly more 
enjoyable.

I suspect a lot of the ugliness in the Oracle stuff is because their 
competition is largely other hugely expensive databases like SQL Server, 
which are *also* incredibly wart-filled, because they're all based on 
really really old code and have been maintained for decades by people who 
care more about getting the next version out and getting a new marketing 
buzzword implemented than they do about internal consistency.

(e.g. Oracle's 'object oriented' features introduced in Oracle 8. There 
are *still* bugs in there whereby unprivileged users can crash entire 
database instances. They *still* don't implement inheritance as far as I 
can tell. It's *still* nearly useless for any practical purpose... because 
it was never intended to be *used*: it was just a marketing buzzword, 
when 'object oriented' was the latest big thing.)
