Instructions for Problem 1:

(1) Create business rule(s) for the assigned business scenario. You are FREE to make YOUR OWN assumptions clearly state your assumptions. Remember: for each relationship, you need to state from both directions.

(2) Based on the rules, create the ER diagram (ONE diagram reflecting all rules).

(3) Then make a/some change(s) in the assumptions that will lead to change(s) in cardinality (or even the relationship), and create the revised ER diagram.

Notes:

A) All entities are in CAPS;

B) No attribute except keys (PK, FK);

C) All relationships are already given; please do NOT introduce your own relationship; in other words, ONLY depict what is explicitly given.

Business Scenario:
