Oracle as in https://education.oracle.com/  ?  I'm not sure what that has to do with being a CPA or Intuit (which is where youve posted).

Thank you for your reply. I  was asked this question by CEO who was looking to hire CPA for specific assignment.  I assume  that some big company use this system and  like to make sure that you are familiar with it. 

I still don't understand what you're asking, sorry.

Are you looking to hire someone?  This isn't a job posting board.

This forum is for user of Intuits professional tax software programs to look for and provide help to fellow users with the software.

I think he wants to learn Oracle software.

Contact Oracle and ask them.
