Problem is, i have no idea where to go from here. Getting the model
nearly to to 3NF and writing some simple queries is about the extent
of my db-related skillset..

Anyone feel the calling..? ;)


Also, how would this kind of check affect performance? Table 'b' is
our ledger table, busiest one in the app i assume, while 'a' groups
related transactions and holds common info. We inherited the term
voucher for 'a', anyone know if that is(n't) appropriate?

If someone are interested, the actual tables are here:
a: http://trac.lodo.no/wiki/vouchers
b: http://trac.lodo.no/wiki/voucher_lines


Any feedback appreciated,
Isak
