When two instructors teach the same section of a course and each instructor must be listed on the time schedule the realization is that there will be overlapping of entries in the time schedule. The most probable course of action is to avoid merging the instructors with the time schedule. In the instructor's section both the instructor's number and the course number will be primary keys. In the time schedule the time and the time and the course number will both be primary Keys
When each department only offers a single major the space in the major's entries will be underutilized it will be therefore important to come up; with a strategy to prevent the wastage of space. The primary key will be the Major code and it will be the foreign key in the Advise table.
When each faculty can only offer a single major and each faculty member can only advise students on the particular major then still the issue of underutilization of space within the database will emerge. Therefore, a strategy should be devised to prevent the under usage of the space. The issue of under usage of space is even made worse when each faculty only offer one major and each faculty member can only advise students on that particular major and students can only take one major.

The number of credits earned cannot vary because they are independent variables they remain constant all through and there is no possibility for the system to make adjustments where the variables are independent. The use of course codes will require both students and other faculty members to memorize the meaning of codes to avoid confusion.
Instead of a course number, course codes are used to uniquely identify courses. (In other words, department numbers are no longer required for this purpose.) However, it is still important to know which courses are offered by which departments. The codes are important because they are easy to memorize than the numbers.
