The University is wants to develop a database to keep track of its faculty, students, departments, students' major, and courses. Students can have undeclared major $($in which case they have no major$),$ single major, or a double major $($i$.$e$.$ two majors$).$ Departments offer many majors, and its possible for multiple departments to offer a single major jointly. Faculty can work more than department while a department employs many faculty. Faculty teach several courses which students are enrolled in$.$ These courses are offered by individual departments. There is also a requirement that the database keep track of the student ID number, student$$s year, and faculty$$s research area. Draw a class $($UML$)$ diagram for the desired database.
