输入字段 input field
- 这意味着转换本身将与相关的源输入字段进行匹配。
This means that the transformations align themselves with their associated source input fields. - 并非要所有输入字段都会被用到,一些输出字段可能会用来自其他来源的数据来填充。
Not all input fields need to be used and some output fields may be populated with data from another source. - 但是,当某个输入字段是必需的,或者由于该字段是必需的而应该设置为缺省值时,您不应该删除该字段。
However, you should not remove an input field when the field is required or should be set to a default value because the field is required.
