Problem 4. [45 points] Suppose that we have the following requirements for a university database (i) The university keeps track of each student's name (SNAME); student identifier (sio); social PADDR) and phone (PPHONE); birth date (BDATE); gender (gender); class (cLAsS) (freshman, any); and degree program (rRoo) (GA H). Both ssa and student identifier have (ii) Each department is described by a name (oNAME), department code (ocoDE), office number that is used to keep track of students' transcripts: security number (ssN); current address (CADDR) and phone (cPHONE); permanent address sophomore, .. graduate); major department (MAJORCODE); minor department (MINORCODE) (if unique values for each student. (DoFFICE), office phone (oPHONE), and college (OCOLLEGE). Both name and code have unique values for each department. (ii)Each course has a course name (cNAME), description (cDESc), course number (cNUM), number of semester hours (CREDIT), level (LEVEL), and offering department (cDEPT). The course number is unique for each course (iv)Each section has an instructor (NAME), semester (SEMESTER), year (YEAR), course (SECCOURSE), and section number (seCNUM). The section number distinguishes different sections of the same course that are taught during the same semester/lyear; its values are 1, 2, 3,., up to the total number of sections taught during each semester (v) A grade record refers to a student (ssM), a particular section, and a grade (GRADE). dependencies that should hold among the attributes. For example, the phone numbers can Then design relation schemas for the database that are each in 3NF or BCNF. Specify the k to render the specification complete. Design a relational database schema for this database application. First show all the functional determine corresponding addresses and offices. An office can also determine its phone number. attributes of each relation. Note any unspecified requirement and make appropriate assumptions
