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
The object oriented programming languages like C++ and Java were a nightmare for me and my professor rushed off with her lectures so fast that I couldn’t catch up with the syllabus. Then once HwA started helped me out with my programming homework I got more time to understand how the things summed up.
Marissa Tan Student
I actually had a research topic in mind but was unsure of how to frame the research question. The research question assignment expert of HwA has helped me to narrow down the topic to one single question which became the foundation of my entire research. They also helped me with the actual research paper where I got excellent grades.

I am very happy with the timely delivery, value for money and 24x7 availability of the online assignment experts. The tutors assigned really listened to my requirements and delivered the assignment help to my exact specifications. Thank you so much TheReliableTutor
Gartner Student
The earlier service I was using only used to provide me with the codes for the Programming assignment help requested from them. At TheReliableTutor the online Singapore Programming tutors provide notes along with the codes which have helped me understand how the code actually works and explain it to the professor too. It has now become a habit with me too.
Nabilah Lim Student
I was having difficulty in structuring and writing the nuclear chemistry assignment on Balancing Nuclear Equations & Predicting the Product of a Nuclear Reaction. The nuclear chemistry assignment expert guided me through the process in such a way that I not only finished writing the assignment but also acquired a clear concept of the topic.

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
