Tim, If you wish to describe each type of cancer by different set of question items, then yes - you should have separate/distinct forms for each. > So in OIO data for each type of cancer is stored in a separate table? Could be - if that's what you want. On the other hand, maybe you can get away with describing all possible cancer case using the same form? Or, you can have a first form that contains common questions (across all cancer types). Then, a special form for each cancer that contains all the cancer-type-specific questions. > Say there are 50 types of cancer of interest (that's an underestimate). > So to create a frequency distribution of type of cancer, I need to write > a query which visits 50 tables? Not at all, OIO's reporting module can do that for you. > Sure it would be better to record type of cancer as an attribute on a > single "cancer Case" form, Yes, you can do that too.

Or 2) define a workflow that contains fillout first form, branch-on-condition, then fillout second form (selected based on answer to cancer-type question on the first form). There is a screeshot with example of this type of workflow here: http://www.zope.org/Members/aho/Open_Infrastructure_for_Outcomes/OIO-1.0.0%20released There is actually a demo workflow on the LiveOIO CD that does this.
