Exercise 5.2 Suppose that we reconsider our STUDENT example, and the only attributes of student are student number and name. Let us suppose that we have another entity called HIGH SCHOOL that is going to be the high school from which the student graduated. For the HIGH SCHOOL entity, we will record the high school name and the location (meaning city and state). Draw the ER diagram using the concise form (as in Figure 4.1c) 113 entities Exercise 5.3 Suppose that a college had one dormitory with many rooms. The DORMITORY entity, which is actually a "dormitory room entity since there is only one dorm, has the attributes room number and single/double meaning that there are private rooms and double rooms). Let us suppose that the STUDENT entity in this case contains the attributes student number, student name, and home telephone number. Draw the ER diagram in the Chen-like model linking the two entities. Name your relationships. Write the grammar for the relationship between the two entities
