为了提高性能，JCS在文件磁盘上存储实际缓存数据的同时，会在内存中存储缓存数据键。

To improve performance, JCS stores the cached data keys in memory while storing the actual cached data on the file disk.

如果目标模型跨多个表，数据差异分析还必须考虑数据键和键关系，以便有效地链接数据元素。

Where the target model is spread across multiple tables, the data Gap Analysis must also consider data keys and key relationships to effectively link data elements together.

在这一部分中，您将看到如何生成键，让你存储每个用户会议所用的数据。

In this section, you'll see how to generate keys that let you store data for each user session.

So, in fact, yes, we did confirm that these covalent bond, at least in the case of hydrogen, we have confirmed by the numbers that we are at a lower energy state when we talk about the bonded atom versus the individual atom.

因此，事实上，是的，我们证实了共价键，至少在氢这种情况下，我们通过数据证实了,成键的原子处于能量更低的状态,当其与单个的原子相对比时。
