    Well, what was it: CBO or RBO? Don't leave us hanging like that.

    It was never established during the interview what optimizer the databases used, and at that point I'd heard enough to be sure that this was not the fellow to be working on our data warehouse. Sorry, it'll remain a mystery.

    thats very interesting! i think HBO will introduced in 10i

    by the way:

    CBO = Calendar-Based Optimizer
    RBO = Reality-Based Optimizer
