    Reading what you've said, I have an impression that you don't know Ingres at all, do you? If that's correct, I'm afraid that you'll spend many sleepless nights in the future. Here's how I see it:
    • you don't know Ingres, but you do know Oracle: find someone who knows Ingres and - above all - designed that "database" (i.e. knows tables' descriptions, relations between these tables, data stored within, etc.). That person could prepare Ingres data for you - for example, CSV files - and you'd then "import" them into your Oracle database (using SQL*Loader, external files, whatever). Without knowing WHAT is stored in Ingres, I have no idea how would it be possible for you to create a data model in an Oracle database that would successfully accept Ingres data in a meaningful manner.
    • you don't know Ingres, and you don't know Oracle: impossible mission, find something else to do
    • you know Ingres, but you don't know Oracle: I don't think so, at least the first part.
    • you know Ingres and you know Oracle: not very likely, otherwise you wouldn't be here asking questions you ask

    So, it seems that there are not that many options there.
