Dimensions are data warehouse constructs. They are implemented as tables in the database, but have the characteristic of a hierarchy that can be traversed. For example: a time dimension can have the hierarchy of date, day, week, month, quarter, year, decade, century. This is used for rollup reporting within the data mart. I don't see any good use of it in an OLTP environment, but I may be wrong.

I have tried, but haven't found a good example of how to _use_ a dimension in 9ir2. I defined one, but then sat clueless on what to do with it. Is it any good in an OLTP environment? (I smell the answer is a NO, but still) ...

Any notes from your experience?

TIA
Raj
