For example, in the data repository tier, staging and repository databases can be on different servers, on the same server, or even in the same database under different schemas.
例如，在数据存储库层，登台数据库和存储库数据库可以在不同的服务器上、在同一服务器上或者甚至在不同模式下的同一数据库中。

As part of this process, the data that is gathered from the sources and being transformed might need to be persisted temporarily in so-called staging areas.
作为这个过程的一部分，收集到的来自不同数据源的并经过转换的数据，可能需要暂时保存到所谓的暂存区。

当表示客户的每个数据块到达本地计算机以进行处理时，数据块将临时放在临时目录中。
In this mode, the secondary reads data from the staging file and receives new data from the primary directly.
在这种模式中，次要服务器从暂存文件中读取数据，并从主要服务器直接接收新数据。
The secondary keeps data for each log file in a separate staging file.
次要服务器将每个日志文件中的数据保存在单独的暂存文件中。
Primary in to files in the staging directory. It immediately acknowledges receipt of the log data buffer to the primary before it actually applies or stages it.
主要服务器将使用暂存目录中的文件，并在实际应用或暂存将保存到主要服务器的日志数据缓存之前，应立即识别对它的接收。
When a piece of data or content element needs to be translated before it can be published on the site, it is populated to the staging server first.
当一段数据或内容元素需要在网站上发布之前被翻译，则首先需要将其传给分段服务器。

Unsupported database staging table - a CCD target table is also an ideal method for getting data to databases outside of Q Replication's supported structure.
不受支持的数据库登台表——对于将数据放到QReplication受支持的结构之外的数据库中这一任务而言，CCD目标表也是一种理想的方法。
This staging table can reside, for example, at an ODS (Operational Data Store), where other data needed for the transform job may also be gathered.
该分级表可以驻留在如ODS (OperationalDataStore) 上，在这里保存有转换作业所需的其他数据。

在求出单级临界压比的基础上，可以计算出级组的临界压比，为在汽轮机变工况在线计算和故障诊断提供数据。
Staging Engine implements data mapping and transformation. Triggered by BW Scheduler, it sends requests to a source system for data loading. The source system then selects and transfers data into BW.
数据加载引擎执行数据映射与转换，并被BWScheduler触发，它发送加载数据的请求给源系统，然后源系统选择数据并传输到BW。
