What do YOU think the answer is? We don't do your homework for you.

This is not for my homework. This question was asked in a National level selection test with these four options and the correct answer key was later published to be option (B) without any explanation given. But I had doubt. I wanted to know why (B) is correct (if it is, really) and why the other three are wrong. That is why posted this question. I wanted an open debate on this issue. I wanted to know what other people and experts like you have to say in this regard. But see what I'm getting from you. I joined this site for a purpose. I'm going to sit for the exam. I expected to learn more from here, expected to have discussions with experts that would have enriched me. But nobody is interested. This is the very first question I posted, and I must say that I received a very warm welcome from you people!! Thank you for such a kind behavior and for wasting your precious time in writing a one-liner reply. Hope you would forgive my audacity of posting such 'crap' here. I didn't know that asking something is such a crime.

Before getting upset with us, read what you wrote and think about this: Just posting a question tells us you are looking for the answer instead of getting help understanding the question and its correct answer. Where is your marking what is supposed to be the correct answer? Where is the request for help in understanding the answer?

Data Integrity control uses _______
(A) Upper and lower limits on
Numeric data.
(B) Passwords to prohibit
Unauthorised access to files.
(C) Data dictionary to keep the data
(D) Data dictionary to find last

Why do you doubt that B is the correct answer? Understanding your thought process will help us guide you in understanding the answer.

First, if you read the rules of this site before jumping in you might have noticed the rules about homework question. As Needkarma said, how am I to know, based on the little that you posted, that this was not a homework question. No, "asking something" is not a crime, but the nature of a question does matter. If you have any anger to be directed it should be at yourself for a) not familiarizing yourself with the site rules and b) not spending more time explaining your question. You criticize me for the brevity of my response when it was the brevity of your question that is the real issue. And, sitting for an exam, still means that this is schoolwork or learning and the same rules apply. If you wanted a discussion about this, then you should have worded your question more appropriately.

I don't need to forgive you for asking, but I do think you owe us an apology for the tone of your response.

While I don't agree with B as the correct answer, it is one of 2 possibilities. You can eliminate C & D as a Data Dictionary has little to do with maintaining data integrity. While A does refer to maintaining data integrity, it is only one possibility of a data integrity control. So, by process of elimination we arrive at B, which is a poor answer because it assumes that the user will know how to maintain data integrity. It assumes the user will only be granted access if they know how and are trusted to do so.
