數据元素或者數据字典,這樣可以讓數據庫的字段名可以有統一的標簽名

在red1上看到的一段解释:

System Element basically means that there is a reference for your new field. With that reference, the system will be able to track that field internally. This is because in the software, tracking is vital and is often the problem. This problem is called Persistence. The element must be the persistence object so as to be tracked. Without it, you cannot refer to it in an efficient manner and will be long winder repeatedly whenever you need to arrange that field for printing or storing. Hope you understand what i am trying to say, but its just an internal issue, and the user like your should not be bother with it. I think in future the element will become transparent and hidden from you.
