Hi Medi,
We may be well off-topic for Pgsql but it is a modeling issue so I'll
reply on-list..
Consider this scenario: You want to track your AP/AR accounts by
"business unit" - so you have a Marketing account, Sales account,
Engineering account, etc. But let's say you want to keep all the money
for all the "units" in only two bank accounts depending on which region
the expenses will be paid out from (to reduce processing fees). So you
might pay for things accrued by Engineering and Marketing on the West
Coast from one bank account and Engineering and Marketing expenses on
the East Coast from the other (a US-centric example).
So the bank accounts where cash is actually deposited/withdrawn is
different from where the money is received or spent from a "logical"
perspective in the AR/AP ledgers.
This is a simple example and real-world issues become truly horrendous.
(For example, try to account for investment instruments like long term
property holdings with lines of credit against the real estate).
I've always thought that if DBA's existed when Accounting was invented,
things would look very, very different. :)
Good luck,
Steve
