read-back check
解釋
讀后校驗-
Think about it : when accessing data from a file, the programmer would have to code instructions to open the file, start a loop, read a record, check whether the empno field equals the proper value, check for end of file, go back to the beginning of the loop, and so on
想想看:當訪問文件中的數據時,程序員必須編碼指令來打開文件、開始一個循環、讀取記錄、檢查empno欄位是否等於適當的值、檢查文件結尾、回到循環的開頭等。 -
Check, read - back
