For a department, store its number and name. b. For an advisor, store his or her number, last name, first name, and the department number to which the advisor is assigned. c. For a course, store its code and description (for example, DBA210, SQL Programming). d. For a student, store his or her number, first name, and last name. For each course the student takes, store the course code, course description, and grade earned. Also, store the number and name of the student's advisor. Assume that an advisor might advise any number of students but that each student has just one advisor. Design the database for the preceding set of requirements. Determine any functional dependencies. List the tables, columns, and relationships. In addition, represent your design with an E-R diagram.The relational schema shown below is part of a hospital database. The primary keys are highlighted in bold.

This particular university has multipledepartments. Each department in that university offers one or more courses to the students. All thestudents are part of a certain department and they take courses in that department. A department hasa name, unique number and chairman. The courses have a name, a course number such as ‘311’ , acredit point value, and the year it commenced. A course cannot be identified uniquely with thecourse number, but the course number is unique for each department. Students have given names,surname, unique Student ID, Date of Birth and the year they enrolled. When a student takes a coursethe year and the semester he or she took that particular course is recorded. When he finishes thecourse , the grade and total marks are recorded. A student can take multiple courses but they are alsoallowed to drop a semester in that university by taking no courses.
