便宜：使用模拟数据库进行测试和调试使您节省了在每个开发人员的桌面上安装DB2(比方说)的成本。
It's cheap: Using a simulated database for testing and debugging saves you the cost of putting DB2 (for example) on every developer's desktop.
在这里，我们可以模拟数据库连接对象的查询方法，这样我们就只需要返回结果，而不需要真正地去查询数据库。
In this case, we would mock the query method of the database connection object so that we could just return back the results instead of calling out to the database for them.
例如，模拟数据库是一个简单对象，但具有数据库的API，可以接受一些已知的sql字符串，并为每个字符串返回一组固定的结果。
For example, a mock database is a simple object with the API of a database that accepts a few known SQL strings and returns a fixed set of results for each one.
研究表明，迄今为止，计算机模拟的可变性比从代理记录中获得的数据要小得多。
Studies suggest that to date the variability in computer simulations is considerably smaller than in data obtained from the proxy records.

如果希望使用实际生产数据运行模拟，则可以从XML中将其导入，这样就不必手动创建每个业务项实例。
If you want to run a simulation with actual production data, you can import it from XML so that you do not have to create each of the business item instances by hand.
收集了模拟业务流程所需的所有数据后，您发现了图4中所示的流程瓶颈。
After collecting all the data you need to simulate the business process, you discover the process bottleneck depicted in Figure 4.
现在应该上载其他XML文档，这些文档包含加拿大和美国一些地区的模拟市场营销数据，后面将用这些文档运行XQuery 和XPath搜索。
Now is the right time to upload the remaining XML documents containing simulated marketing data for a few regions in Canada and US to be used in exercising some XQuery and XPath searches.

When the simulation runs, the data for the Rehire field gets passed through the first task so it can be used by the decision.
火控系统与传感器数据结合，生成精确的目标坐标，然后模拟出路基拦截器击落目标的过程。
The fire control system combined the sensor data, generated accurate targeting coordinates, and simulated a target shootdown with a virtual ground-based interceptor.
不过，在进行模拟时，该流程将不会释放它的数据，因为涉及Task2和Task 3的分支不是以停止节点结束的。
However, the process will not release its data in the simulation because the parallel branches involving Task 2 and Task 3 do not end with a stop node.
