Question 2
This question assesses your ability to produce an initial structural model form a given NSR (negotiated statement of requirements). You should be able to complete the question after studying Chapters 33 and 34
A college academic contest day consists of several tracks and fields contest. Each field contest must have at least three competitors, and each track contest must have at least five competitors. Each contest is given a start time during the day, which must be recorded. In addition, a result must be recorded for all track contests, and the type of a field contest (art, math, physics, etc) must be recorded for field contest. Each contest is organized by a single teacher, and a teacher may organize one or more contest. The name of the teacher is recorded by the system and is considered to be unique.
A competitor must compete in exactly two field contests and two track contests. In order to be eligible for an contest the competitor must have qualified to take part in the contest. The date on which they qualified must be recorded, along with the name of the teacher who witnessed the qualification attempt (the competitor must pass 50% of the trial questions). A teacher can witness as many qualifications as they wish. However, a teacher may only witness qualifications for contests that he or she organizes. A competitor must qualify separately for each contest, but he or she may choose not to participate in a contest that he or she has qualified for. A unique competitor's number is recorded for each competitor, along with his or her age.
Purpose
The Academic contest Day system will provide support for the college in the following way:
Track, Field, Qualification, Teacher
The above list is incomplete; the negotiated statement of requirements indicates that two more classes are appropriate for inclusion in the initial structural model.
For each additional class:
State a suitable name for the class and classify the category of real-life objects modelled by the class as one of the following: tangible object, role, event or organisational unit.
(ii) Produce a class diagram and class descriptions for an initial structural model for the Acadimic contest Day system. This should involve the classes listed above, along with the classes identified in your solution to part (i), and no other classes. In your TMA document included
(a) The class diagram
(b) The class descriptions, including a brief comment for each attribute and comments indicating any inheritance structure.
(iii)
(a) State formally (that is in terms of instances of classes and associations an invariant that expresses the fact that if a competitor has entered for a contest, he or she must have qualified for it.
(b) State formally one other invariant not one expressing the uniqueness of an attribute value, that is required in your initial structural model
Notes
If you find the arrow indicating a generalisation relationship difficult to produce in a word-processed solution, then you may use a different kind of arrow, so long as the relationship you are depicting is clear from your class diagram and descriptions.

Purpose
The Academic contest Day system will provide support for the college in the following way:
- In response to a request for a list of competitors, the system will provide the name and age of every competitor who has entered an contest.
- Given the unique identifier of a competitor, the system will provide a list of the track and field contests for which the competitor is qualified.
- Given the contest result or type, together with the start time, the system will provide details of the competitors who have qualified for the contest.
- Given the unique name of a teacher, the system will provide a list of contests, which he or she is organizing.
