这不仅能够节省时间,还能够保证数据服务消费者在准备数据服务的输入或解析数据服务的输出时,对数据实体有一个一致的定义。
This will not only save time but also ensure that the data service consumer has a consistent definition of the data entity when preparing inputs or parsing outputs from data services.
不过,在一个交互式应用程序中,对数据的更改可能更动态;如果用户已经登录了很长时间,那么他会希望在发生数据变更时有所反映。
However, in an interactive application, changes to data might be more dynamic; if a user is logged on for a long period of time, then he might expect changes in data to be reflected when they occur.
所以,如果您要在给定时间范围内清理数百万个地址,可通过支持您对数据进行分段的方式来应用规则。
So if you are cleansing millions of addresses within given time bounds, rules can be applied in such a way that lets you segment the data.
在您收集了响应时间分解数据后,就可以使用性能分析工具对数据进行分析,以便确定哪部分代码导致了问题。
After you have collected response time breakdown data, you can analyze the results in the profiling tools to identify exactly what part of the code is causing the problem.

Such a move would also raise the question of what should be done with millions of schoolchildren during a prolonged shutdown, they added.
奥普拉:你知道,我开始觉得,当我……当我面临这个选择的时候,你知道,我问自己是否要把离开的时间定在二零……,你知道我对数字很敏感。
Oprah: You know, I actually started to feel it when I…when I had the option, you know, well, the question was do I leave in two thousand and…you know how I like numbers.
这减少了对数据库服务器中应用进行问题诊断与追踪的时间和工作量。
This reduces the time and effort needed to diagnose and trace a problem from the application through to the database server.
延时:初始化一个对数据的请求到数据真正开始传输的时间。
Latency: the time between initiating a request for data and the beginning of the actual data transfer.
然而,保留了初始时间,以对数字进行保守估计。
However, the original times were kept, to keep the Numbers conservative.
就像我知道随着时间的流逝,我这个年龄段在男性眼里会变得越来越没有魅力一样,而这个年龄段的男性却还可以对数不清的更年轻的有生育能力的女人挑挑拣拣。
Just as I am fully aware that with each passing year, I become less attractive to the men in my peer group, who have plenty of younger, more fertile women to pick from.
timeron不直接等于真正的消耗时间,但是对数据库管理器所需的资源(成本)给出了一个相对粗略的估算。
A timeron does not directly equate to any actual elapsed time, but gives a rough relative estimate of the resources (cost) required by the database manager.
IBMDB 2提供了一些技术和配置,可用于实现弹性和有保障的恢复时间,以及允许对数据库上的负载进行分配。
IBM DB2 offers several technologies and configurations that can be used to achieve resiliency and guaranteed recovery times, as well as allowing the load on the database to be distributed.
我的高中数学老师KathCloud花了很多时间去寻找我能理解的方式来为我讲授数学,在我到Cloud的班里学习之前,我一直对数学学习很痛苦,是她给了我信心,让我相信自己能够学好数学。
My high school math teacher, Kathy Cloud, took the time to explain math to me in a way I could actually understand. I’d struggled with math until I got in Cloud’s classes.
在他再次对数学着迷之前,Gentry知识产权律师的身份工作了差不多两年的时间。
He worked as an intellectual property lawyer for less than two years before feeling the math bug again.
由于数据分散的原因,当Fours quare试图增加一个分区时没有成功,需要数据库离线才能对数据进行压缩。这也导致了系统宕机时间的延长。
The system outage was prolonged when an attempt to add a partition didn't work due to fragmentation, and required taking the database offline to compact it.
它比write - through缓存具有更快的响应时间,后者对缓存的更新会导致对数据库的及时更新。
This scenario also has faster response times than the write-through caching scenario where an update to the cache results in an immediate update to the database.
如果这个问题的规模,也就是n,是,如果这个问题是对数级的,这将会占据10纳秒的时间,你一眨眼的时间。
If I'm running at nanosecond speed, 1000 n, the size of the problem, whatever it is, is 1000, and I've got a log algorithm, it takes 10 nanoseconds to complete.
以联动轴数作为输入考察插补速度,算法时间复杂度是对数阶的。
The algorithm running time is a logarithmic function of the number of linkage axes.
结果表明,沉降速率与沉降、剩余沉降均呈线性关系,沉降速率的对数与固结时间成正比。
The result indicates that the relationships between settlement-velocity and settlement, remnant settlement are linear, and logarithm of settlement-velocity is linearity with consolidated time.
