To: "BLU Discuss" <discuss@blu.org> Hello, I'm writing some personal finance management software, and I'm puzzling over the best way to keep track of the balance for each account. I've got an accounts table and a transactions table. I need a way to get the balance for an account, but the current balance depends on the value of all transactions tied to that account from now until the beginning of time. Obviously summing all transactions for that account is not the most efficient way of finding the current balance. The alternative is to add a balance field to the accounts table and create a trigger on insert, update or deletion in the transactions table to update the appropriate account balance. The risk here is that, somehow, this will get screwed up or out of whack and then the account balance won't correctly reflect the sum of all transactions for that account. Resetting it would be easy (just re-sum all transactions for that account) but adding this feature would be offensively kludgey to me. I've considered a few other options but none of them really sit right with me. Should I just add the trigger to my DB and trust that (if properly programmed in the first place) it will always work? Thanks, Daniel _______________________________________________ Discuss mailing list Discuss@blu.org http://lists.blu.org/mailman/listinfo/discuss _______________________________________________ Discuss mailing list Discuss@blu.org http://lists.blu.org/mailman/listinfo/discuss
