We have an (over simplified) university database, with attributes CLASS, SECTION, STUDENT, MAJOR, INSTRUCTOR, RANK, SALARY, and TEXT. Intuitively a given CLASS (such as IS702) is divided into SECTIONs (such as Section 2) each of which has one INSTRUCTOR and various STUDENTS. Each CLASS has a set of TEXT BOOKS, which are used by all SECTIONS of the CLASS. Each STUDENT has one MAJOR. Each INSTRUCTOR has one RANK and one SALARY. Starting with one relation: R(CLASS, SECTION, STUDENT, MAJOR, INSTRUCTOR, RANK, SALARY, TEXT) Find all non-trivial functional and multi-valued dependencies Decompose into 4NF (and hence BCNF)
