Consider the following set of requirements for a university database that is used to keep track of students' transcripts. Create Conceptual and Logical Schema
a. The university keeps track of each student's name, student number, social security number, current address and phone, permanent address and phone, birthdate, sex, class (freshman, sophomore, ..., graduate), major department, minor department (if any), and degree program (B.A., B.S., ..., Ph.D.). Some user applications need to refer to the city, state, and zip of the student's permanent address, and to the student's last name. Both social security number and student number have unique values for each student.
b. Each department is described by a name, department code, office number, office phone, and college. Both name and code have unique values for each department.
c. Each course has a course name, description, course number, number of semester hours, level, and offering department. The value of course number is unique for each course.
d. Each section has an instructor, semester, year, course, and section number. The section number distinguishes different sections of the same course that are taught during the same semester/year; its values are 1, 2, 3, ...; up to the number of sections taught during each semester.
e. A grade report has a student, section, letter grade, and numeric grade(0, 1, 2, 3, 4 for F, D, C, B, A, respectively).
2. Create a Conceptual and Logical Model using the following requirements.
For keeping track of information about votes taken in the U.S. House of Representatives during the current two-year congressional session. The database needs to keep track of each U.S.STATE'S Name (e.g., Texas, New York, California) and include the Region of the state (whose domain is {North-east, Midwest, South-east, Southwest, West}). Each CONGRESSPERSON in the House of Representatives is described by his or her name, plus the District represented, the StartDate, when the congressperson was first elected, and the political party to which he or she belongs (whose domain is {Republican, Democrat, Independent, Other}). The database keeps track of each BILL (i.e., proposed law), including the BillName, the DateOfVote on the bill, whether the bill PassedOrFailed (whose domain is {Yes, No}, and the Sponsor (the congressperson(s) who sponsored-that is ,proposed-the bill). The database keeps track of how each congressperson voted on each bill (domain of vote attribute is {Yes, No, Abstain, Absent}). Draw an ER schema diagram for this application. State clearly any assumptions you make
