inquiry
backup
update
programming E. None of the above
Answer is Right!
Answer is Wrong!
The correct answer is D. programming.
On-line direct-access systems are computer systems that allow users to access and update data directly, without the need for a programmer to write a program. The three primary functions of on-line direct-access systems are:
- Inquiry: Users can query the system to retrieve data.
- Update: Users can update data in the system.
- Backup: Users can back up data from the system.
Programming is not one of the three primary functions of on-line direct-access systems because it is not necessary for users to be able to write programs in order to use the system.
