Normalization Of Relational Database Management System
Question
Consider the relation R, which has attributes that hold schedules of courses and sections at a university;
R = {CourseNo, SecNo, OfferingDept, CreditHours, CourseLevel, InstructorSSN, Semester, Year, Days_Hours, RoomNo, NoOfStudents}.
Suppose that the following functional dependencies FDs hold on R:
{CourseNo} → {OfferingDept, CreditHours, CourseLevel}
{CourseNo, SecNo, Semester, Year} → {Days_Hours, RoomNo, NoOfStudents, InstructorSSN}
{RoomNo, Days_Hours, Semester, Year} → {InstructorSSN, CourseNo, SecNo}
Try to determine which sets of attributes form keys of R. How would you normalize this relation?
Summary
The question belongs to Computer Science and it is about writing a query for database normalization. The relation between courses, sections and university have to be given in the normalization query.

WHAT OUR STUDENTS SAY
1. Without TheReliableTutor.com I would have been in deep soup, what with the assignments due on geometry, algebra, trigonometry on my undergrad. Keeping up with all the assignments along with keeping up with the homework assignments was proving to be a bit too much for me to manage on my own. The professors were helpful but not always easily available for consultation. The tutors at TheReliableTutor.com are available at all times to answer my queries and I feel so much calmer now and my grades have improved dramatically!

I ordered my zoology assignments to these guys. First I was reluctant to pay them. However after the initial payment, they provided me a draft of work. I was indeed amazed with the work quality and I ordered for the rest.

I had an optical networking assignment due along with two other assignments due around the same time. I was just not getting enough time to give for dedicated research on the optical networking assignment. I just wished that someone could take the responsibility of conducting the research on my behalf and structure the assignment also. One of my friends was using TheReliableTutor.com and told me to give it a go. I was so impressed by their quality and service standard that I have become a repeat customer.

When I saw the prices of TheReliableTutor law assignment help for New Zealand students I was very skeptical of the quality. But I still gave them a try and lets just say that the quality has been even better than what I had expected. Since the legal assignment experts are practicing professionals from New Zealand they know exactly what is happening in the New Zealand legal world at the moment and help incorporate those into your law assignment and law homework.

When I saw the prices for civil engineering online tutoring with HwA I was not really sure what the quality of the tutoring would be like. But I was very impressed by the panel of civil engineering tutors at HwA and have already greatly benefited from the online tutoring sessions on Urban Engineering and Structural Analysis.

Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
