1. .. The following set of brief scenarios describes the relationships between various entity classes. Draw the entity classes (only show entity name - no attributes or identifiers) and the relationship making sure to add notation (use any standard notation) that shows reasonable minimum and maximum cardinalities given the implied scenario. All scenarios will only have one relationship. The one relationship may be between a maximum of two entity classes (binary) or between an entity class and itself (recursive). If you make any assumptions beyond what is stated be sure to note that in your answer. C. A university is organizing a student trip. They are constructing a database (to be used for this specific trip only) to store the students who sign up for the trip as well as the relationship of each student to their assigned student leader. The database stores a list of students who will be going on the trip. One of the students on the list will be assigned as a student leader for every group of 20 students on the list. Student leaders are designated at the same time they are assigned students so it is an mandatory relationship. Design all entities and relationships required to obtain the list of all students and also the list of students have been assigned to a student leader. Each student who is not a student leader is assigned to zero to one student leaders. This is an optional relationship since the students sign up for the trip and need to be put into the database long before they are assigned a student leader. 1. ..
