please draw the E-R data model

2. Create relationships between entities based on the following facts: - Each student is assigned one and only one faculty adviser and must have an adviser. One faculty member may advise several students, but faculty members are not required to advise students. Only the fact of this assignment is to be recorded in the data model-not possible related data (such as the date the adviser. was assigned to the student). Each student may be assigned one and only one mentor, but students are not required to have a mentor. One mentor may mentor several students, and a person may be listed as a mentor before he or she is assigned students to mentor. Only the fact of this assignment is to be recorded in the data model- not possible related data (such as the date the mentor was assigned to the student). Each mentor is assigned to work and coordinate with one and only one faculty member, and each mentor must work with a faculty member. One faculty member may work with several mentors, but faculty members are not required to work with mentors. Only the fact of this assignment is to be recorded in the data model-not possible related data (such as the date the faculty member was assigned to the mentor). Each mentor may be an alumnus, but mentors are not required to be alumni. Alumni cannot, of course, be required to become mentors
