数据库相关英语翻译(1)

目标语句：原子性提交意味着在一次事务中，所有对数据库的改变或者全部发生， 或者什么也不做。

官方原版： Atomic commit means that either all database changes within a single transaction occur or none of them occur. 

俺的：atomic commit means the modifications on database occurs it all, or else nothing happens in one transaction.

总结：

1.change从词性上看确实也是可以作名词的！database这里算作定语了？

2.要么。。。要么，果然应该用either....or...

3.主语为change，其他的类似于“一次性事务”这样的词组尽量用其作为修饰

目标语句： 通过原子性提交， 就好像对数据库文件中很多不同部分的写入同时、立即发生。

官方原版：With atomic commit, it is as if many different writes to different sections of the database file occur instantaneously and simultaneously. 

俺的：Through the atomic commit, just like the writings of different parts in database file are happens simultaneously.

总结：

1.“通过”指使用某种方式，可以用with来表示

2.注意用从句表示某件事情，这里“many different writes to different sections of the database file”作为主语表示发生的事情。

3.立即发生==“instantaneously ”

目标语句：  真正的硬件会将数据连续地写入磁盘，并且每写一个扇区都需要一定的时间。

官方原版：Real hardware serializes writes to mass storage, and writing a single sector takes a finite amount of time. 

俺的：The specific hardware will write data continuously into disk, and it need some time for every section.

总结：

1.“连续地写”技术性上就是串行写入，这里serializes 的是write操作，主语是硬件，谓语是seralize

2.必要条件下，不需要用it指代，而是直接用现在时词组作为主语，“writing a single sector ”

3.需要时间，即耗费时间，一般的用法确实是用take 。。。 time或者cost time，除非是某人耗费时间在什么上才用spend time on

目标语句： 所以，不可能真正实现多个不同的扇区立即、同时的写入。 

官方原版：So it is impossible to truly write many different sectors of a database file simultaneously and/or instantaneously.

俺的：So it is impossible to realize the actual different sections wring immediately and simultaneously.

总结：

1.write不是一定要作为进行时才能使用

2.多个不同，翻译为many different

3.“真正写入”， 表示为truly write,显然比名词指代这件事情更形象。

目标语句： 但 SQLite 中的原子性可以让所有的写操作看起来都是立即地、同时地。

官方原版：But the atomic commit logic within SQLite makes it appear as if the changes for a transaction are all written instantaneously and simultaneously.

俺的：But the atomic attribute in SQlite could make all of the wrings looks like at the same time.

总结：

1."让...看起来"，make itappear as if that

2.“所有的写操作”，the changes for a transaction are all written
