Oracle is not an option. It usually isn’t. Way overpriced for what it does, more hype than substance.
“...and no we’re not going to move on to some other database system. There are no guarantees that any other system can do a better job”
That’s very true in general in the software industry; changing X for Y without knowing first if it will do better is a bad idea.
I was the Project Manager for bringing a Government Corporation from a 16 bit system to Oracle 8i and putting them on the web with a total interface that allowed people to register and manage their accounts on line.
In its place, Oracle is useful if you need a normalized database with quite a few bells and whistles. I do not think that the FR site requires a normalized database and that would only make things more expensive and a waste of time and precious money.
