推荐答案

首先，研究一下UPS(不可间断电源)

First, look into a UPS (un-interuptable power supply)

第二，研究创建持久性事务，这些事务将尽早且经常保存，但是直到您告知时才提交.这超出了TSQL中的典型事务.

Second, look into creating persistent transactions, transactions that will save early and often, but not commit until you tell it to. This goes a little beyond the typical transactions in TSQL.
