2. Create an entity-relationship diagram (ERD) based on the following information.

At a community college, courses are offered as course sections but some semesters some courses might not be offered. In order to manage these courses, selected faculty members are served as courses coordinators. One faculty member is assigned as course coordinator to oversee the course, and each faculty member can be coordinator of many courses. A student enrolls in many course sections and each course section contains many students.

For each ERD, identify reasonable entities and their relationships (one-to-one, one-to-many, or many-to-many) using the crow's foot notation described in Chapter 2 of Kendall & Kendall 9th textbook among these entities.
