Hello, I'm looking for a little input on this situation.
I'm working on an inventory system and was thinking that I'd like to
build it similiar to the way a bank keeps track of your funds.
If you look at at bank statement, for each line item, you'll normally
see at least date/time, description, amount (plus or minus value), and
balance.
In my inventory system, the amount and balance would be a count of the
items used or transferred instead of money.
Does this sound reasonable? Or is there a better design? I am planning
to connect the inventory system to a few different ordering interfaces,
and I think it would work well if I can dump transactions into the
inventory instead of incrementing and decrementing counts.
The only problem I see with this, is if I want to implement the balance
part of it with each record....
I can't think of a way to do that currently.
I can certainly use a trigger in the database to retrieve the most
recent transaction and update the balance field for one record inserted
at a time, but if a list of transactions is dumped into the inventory
system at once, I'd have to compensate for that in the trigger.
Ideas?
