Re: Oracle 11i Data Model

Almost every "Apps" DBA has had this issue at one point or another. Remember that Oracle "Financials" (which evolved into E-Biz Suite) started way back in the good ole days of Oracle V6 when referential integrity was not supported (i.e. it was called "declarative" in that you can declare it, but the RDBMS would ignore it). I believe some of the later modules (HR comes to mind) do have that, but the older modules do not.

Anyway - Rel 12 is already out and "Fusion Confusion" is apparently around the corner. Would be interesting to see if Fusion does have this information.... (Don't think Rel 12 does).
