I'd jump at the chance to know why most Banks or Financial organizations favor Oracle than different RDBMS for their center frameworks (the totally least highlights that a Bank must help). I found a couple of answers that didn't fulfill me. For instance: Oracle has more highlights. In any case, highlights for what? Wouldn't you be able to execute that in application level in the event that you were not utilizing Oracle?

Might someone be able to please portray more specialized yet on abnormal state diagram of what the bank needs and how Oracle Financial  would explain it and the others can't or don't have the highlights yet?

Minor inquiry: would you utilize ORM on the off chance that you need to build up a keeping money arrangement?

I originated from the web-application (web 2.0) swarm who typically hear news about MySQL, PostgreSQL or even key-esteem/section situated capacity arrangement. I have very nearly zero information on how Banks or Financial organizations works from specialized point of view.

I think that is for these reason: DRP features cover with data guard, HA whit Oracle RAC with active- active instances ; ASM storage, and with very aggressive offer to the market; also in the financial market is very closed to new changes in tecnologies or migrate to differents vendors and existing system in almost cases that I worked the only chage aceptable is an upgrade for the same tecnology vendor.
