one more thing what did u write for why data need be validated after verfication

verification will check that the data inserted has no typing errors and similar but validation checks that the data is resonable and valid

then I gave two examples of validation checks

Advantages of GUI or CLI?

GUI do not need to memorize commands unlike CLI which needs to memorize commands

GUI is faster than CLI as typing commands takes long time and modifing errors takes long time

GUI has WIMP which is Window , Icon , Menu and Pointer

What did you guys put for the last one? I, first, defined EFTPOS and briefly explained what is was and what it did. After, that I was blank so I finished the rest of the paper and went back to this. The only thing in my mind regarding the subject was how a customer were to complete a transaction (at the supermarket) using a EFTPOS terminal. What about you guys?

And also, the question about the analyst. What are the three things he can do to examine the current system? I put observation, questionnaires and interviews.
