More than enough ideas. Thank you _very_ much.
Presenting this kind of 'distributed' data in a useful way is more difficult
(at least for me) but I can see now that this is what _relational_ databses are
all about, and that once you've grasped how to do this, the advantages are
legion.
Many thanks once again.
