問題文

A vendor creates the specification of a package in a customer database and leaves the body for a later delivery, and a developer of the customer wants to compile a program that calls the package in the meantime. Which description of what can be compiled at that point is correct?

選択肢

  1. The specification is stored with the body as one object when the body is created, and a program that calls the package needs both of them, so the specification alone cannot be created in the database at all.
  2. The specification stands as an object on its own once it has been created, and a program that calls the package needs the body rather than the specification itself, so the program of the customer waits for the body to arrive.
  3. The specification stands as an object on its own once it has been created, and a program that calls the package needs neither of the two until it runs, so the program of the customer compiles even before the specification arrives.
  4. The specification stands as an object on its own once it has been created, and a program that calls the package needs the specification rather than the body, so the program of the customer compiles before the body arrives.
