It depends what you want to do. Sometimes this may be the case. However, entering data directly into a database by typing in information has some difficulties and drawbacks. This may have security advantages. Because of the above, a larger number of people can safely use the computer interview.
Clients can do the computer interview themselves.
Alternatively auxiliary staff can do it. This avoids a member of staff having to be paid to do all data entry themselves. A computer interview with multiple choice options which are clicked, is usually faster than typing in data. Typing errors are eliminated or minimized, which is very important in a database. You can use less powerful computers and may require less software.
