如果我们只抽取数据元素,会得到“0,255,255”,如果您不知道数据定义是什么,那么这种数据毫无意义。
If we simply extract the data elements, we get "0, 255, 255", which is meaningless unless you know what the data definitions are.
因此,如果抽取这些元素并将其放入公共模板,则可以从所有视图调用该模板(通过名称)。
So if these elements were extracted and put in a common template, the template can be called (by name) from all views.
当数据元素出现在我们已经从中抽取数据的数据源中的时候,我们只需要将其添加到现有的抽取代码中。
When a data element occurs in a data source from which we're already extracting data then we merely need to add it to the existing extract code.
