GOAL:

What is a Transaction

FIX:

A group of logically related operations that must be completed atomically, without other activities intervening. Also called Physical Transaction and Common Unit. If any part of the transaction cannot be completed, all completed parts must be undone before execution can be allowed to proceed. A transaction left partly completed causes logical corruption that might be very hard to resolve without extensive and costly analysis. Once implementations add the ability to change data in the proprietary storage system, they must also implement transaction management to protect against data corruption.
