In an atomic transaction, a series of database operations either all occur,
or nothing occurs. A guarantee of atomicity prevents updates to the database
occurring only partially, which can cause greater problems than rejecting
the whole series outright. In other words, atomicity means indivisibility
and irreducibility.[1]
半路出家的,最好把基础知识补了再来。每天纠缠这些常识问题,实在是浪费时间。
居然还问怎么算transaction, 我老不是来做TA的。
