Question

Design a database to keep data about college students, their academic advisors, the clubs they belong to, the moderators of the clubs, and the activities that the clubs sponsor. Assume each student is assigned to one academic advisor, but an advisor counsels many students. Advisors do not have to be faculty members. Each student can belong to any number of clubs, and the clubs can sponsor any number of activities. The club must have some student members in order to exist. Each activity is sponsored by exactly one club, but there might be several activities scheduled for one day. Each club has one moderator, who might or might not be a faculty member. Draw a complete E-R diagram for this Database.

(a) All entities with their attributes must be represented, indicating all candidate keys. You must indicate and justify all assumptions you have made.

(b) Describe non-trivial domains for attributes where needed.

(c) Make a decision about the cardinality and participation constraints of all relationships, and add appropriate symbols to the E-R diagram.
