View Full Version : ragged hierarchies

can hierarchies have skipped levels?
(I couldn't see it in the schema doc although I do see that parent-child hierarchies are handled)

No, not currently. Do you need this feature?

It is something that I have come across many times in real world situations. For my current project I may solve the problem by inserting a dummy level.
I'm giving Mondrian a trial by building reports for Tutos
It's doing pretty well so far and I am very impressed.

OK, I hear you. Can you log an RFE? If you know of other systems which support ragged hierarchies -- e.g. Analysis Services uses a dummy value to indicate a missing level -- and have some ideas how a ragged schema might be modeled in a catalog.xml, please put them in the RFE.
Nice to hear of someone who's using us, and even better to hear that they're pleased with what they're getting! I'm thinking of adding a list of projects/companies using Mondrian to the home page. May I add Tutos?

sorry about that Julian, just drifted off for a month.....re:Tutos I'm only doing that as a trial for Mondrian, so it isn't actually part of that project yet. I've built as much as I can on their existing tables, but now I have reached the limit of what I can get out of it so will need to write an ETL process to pull the data into a proper star-schema. Once i've done this I intend to release it to the Tutos people...i'll tell you if I get to this point.
