Oracle supports a mechanism called Multi-Version Read Consistency which is implemented by undo data in the undo segments.
Oracle支持一种称为Multi - Version Read Consistency的机制，这是用undo段中的undo数据实现的。
If the business requires greater availability but read consistency is not a premium, then an asynchronous option may be a more cost-effective approach.
如果业务要求更高的可用性，并且读一致性不是很重要，那么选择异步可能是更经济的方法。
That's also a costly option, however, because every time you iterate across the contents of the collection, you have to synchronize all operations, including read and write, to ensure consistency.
然而，这也是一个成本较高的选择，因为每当您跨集合内容进行迭代时，您就不得不同步所有操作，包括读和写，以此保证一致性。
Weak/eventual consistency happens when not all data replicas participate in the update operation and/or contacted as part of read operation.
只有部分数据副本参与更新操作，且/或作为读操作的一部分与其它副本进行联系时，就会出现弱/最终一致性。
When strict consistency is not required, create pools of replicated and redundant read data.
在不需要严格一致性时，为要读取的数据做复制和冗余。
If you've chosen to relax consistency, for example, then the developer needs to decide how to handle a situation where a write to the system is not immediately reflected in a corresponding read.
比如说，如果你选择放松一致性要求，那么开发人员就要决定怎样处理这种情形——对系统的写入不会立即反映到对应的读出中。
GSD provides read-after-write consistency which basically means that an object can be accessed - listed, downloaded, or deleted – right after uploading.
GSD提供了写后读的持久性，这意味着一个对象在上传后就可以访问了：列表、下载或是删除。
As long as the session exists, the system guarantees read-your-writes consistency.
只要会话还存在，系统就保证“读己之所写”一致性。
GSD has a few attractive features: data is replicated across multiple data centers and it is backed up, it has read-your-writes consistency, and can accept objects up to 5tb.
GSD包含一些引人注目的特性：数据跨多个数据中心复制和备份，保证读写一致性，最多容纳5tb的对象。
That may not be what your want to hear about in a book on training, but read on to better understand how consistency will make you faster.
这或许不是你想要从书中听到有关训练的内容，但是好好的理解如何达成一致性，将使你骑得更快。
Consistency is key when developing a resume and helps make the information on the resume simple for employers to read.
在写简历的时候，连贯性是关键，这也有利于雇主更容易读懂简历上的信息。
As you've just read, the major difficult for your brain is to reinforce and create consistency, and the best way to help your brain doing it is by recalling what you've just learnt multiple times.
如你刚刚读到的，你大脑的主要困难是强化和创造一致性。帮助大脑做这件事的最好方法是多次回忆你刚刚学到的东西。
Thrown when control information that was read from an object stream violates internal consistency checks.
当从对象流中读取的控制信息违反了内部一致性检查时抛出。
