Is There a Deadlock?

The point of a transaction is to make things easier for you as the developer to handle something when, when your rights or your reads fail. You know, can you imagine if you didn't have a database that was taking care of the stuff for you and you were e-commerce? Like with having an order in the inventory or even moving money from one account to another. I mean, it doesn't seem all that valuable when we're talking about transactions in such a small scope.
