Create an ER diagram for the following situation.
TAMUC is planning to create an online store such that students can order course materials using
this system. TAMUC has several colleges, and each college has several departments with some faculties.
Colleges offer courses in different sections and faculties teach courses. The courses can be
traditional or online. Each faculty can teach multiple courses and in some semesters, they may
teach more than one section of each course. Instructors of course can have different type 01
contracts, which are categorized as lecturers, Visiting faculty and Tenure track faculty. Each course
has ID, unites, start date, end date, section, number of allowed registrants and class. The classes
are across campus in different buildings and they have limited capacities. Each course has
supplementary materials that signed up students for the course need to purchase. These materials
could be Textbooks, Software Applications, and CD which are determined by the instructor of the
course. Some courses may have more than one of these materials. Students need to order materials
and pay the price using one of the allowed payment methods, which are Credit Card, Debit Card,
Bank Account. For each transaction, purchase of items, only one method of payment is allowed.
