Consider the following schema for a student relation. {Student ID, Last Name, First Name, Course ID, Course Section, Course Name, Eaculty. ID. Faculty Last Name, Faculfy_First Name, Faculty Building&Qffice #, Semester, Grade} Sample Data: A43469873, layr, aty, MSIS5662, 01, Data visualization, A98706724, Sarahi, Rohandra, BUS404, SP2022, A In a given semester (Note that there will be multiple semesters): • A student may be enrolled in multiple courses, from multiple faculty, and receives a grade for each • A faculty may teach multiple sections of multiple courses If you make any other assumptions, clearly state them here.

Consider the following schema for a student relation. {Student ID, Last Name, First Name, Course ID, Course Section, Course Name, Eaculty. ID. Faculty Last Name, Eaculfy_First Name, Faculty Building&Qffice #, Semester, Grade} Sample Data: A43469873, layr, arty, MSIS5662, 01, Data visualization, A98706724, Sarahi, Rohandra, BUS404, SP2022, A In a given semester (Note that there will be multiple semesters): • A student may be enrolled in multiple courses, from multiple faculty, and receives a grade for each • A faculty may teach multiple sections of multiple courses If you make any other assumptions, clearly state them here. a. Assuming that the table is in 1NF, identify all candidate key(s) and your choice of primary key. b. Identify the functional dependencies in the 1NF table above based on the chosen primary key, including any partial and transitive dependencies. (If necessary, clearly state your assumptions). In answering this, you may use the format in question 1d. c. After removing partial dependencies, show all tables, that are in 2NF. For each table, give the name, the primary key attribute, foreign key(s) if any, and which primary key of which table the foreign key(s) reference. d. After removing transitive dependencies, show all tables, that are in 3NF. For each table, give the name, the primary key attribute, foreign key(s) if any, and which primary key of which table the foreign key(s) reference.
