CS403 Database Management Systems paper
Total 22 Questions, out of which
16 MCQs of marks 1 each
2 short questions of marks 2 each
2 short questions of marks 3 each (i'm not sure whether there were 2 short questions of marks 3 each or 3 short questions, but what I remember, there were 2 short questions of marks 3 each)
2 short questions of marks 5 each
Some of the short questions that I remember are:
I do not remember the exact statements of questions, but the concept which was asked in questions is as under:
1. For what purpose do we use Relational Data model?
2. What is the difference between Primary key and unique key with reference to null value?
3. Write two sub-categories of outer join?
4. attribute and key attribute, give example as well. (I think the question was, what is the difference b/w attribute and key attribute, anyways, I wrote about attribute and key attribute in answer with one example)
5. Explain union? (marks 5) (page # 152 of handouts)
6. What is first normal form? (page # 167 of handouts)
