A database at a college must support the following requirements:

a$.$ 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, DBA$210,$ 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 fumber of students but that each student has just one advisor.

Design the database for the preceding set of requirements. Use your own experience as a student to determine any functional dependencies. List the tables, columns, and relationships. In addition, represent your design with an E$-$R diagram.
