Design question?

Hi group,

I need to create a component that passes data. (Need more details :D)

A user can select a report. After that the parameters for the report appear. The user can fill the parameters if he chooses to and presses a button [buttonGenerate]

I need to provide a 'datastore'.

Problems:
The reports have a datasource differing from 1 table to 14 tables. I think the only possibillity I have is a dataset.
Is this true?
How should I go about this? Should i create a class that builds the DataSet? :eek2:

Any ideas, tips?

Tia
