Exercise 1: Car Sales
Make the class diagram for the following system. This is a company selling used cars with the following: The cars are supplied by different suppliers, we want to know the make, model, registration, purchase price, sale. Cars can be for tourism, industrial and SUVs. They may also need to be repaired, so it must have control of the repairs made, which may be mechanical, electrical or sheet metal. In the company there are two types of vendors, employees and commission. Of employees we want to know also the wage and commitment that go with cars that were sold. You have control of both the customers who bought a car, as well as those interested in some kind of car you can make a reservation. Cars can be at different exposures, and we always know where each car. Operations are needed to make a sale of a car, to repair cars that need to buy new cars suppliers, etc. Also interested in having us back operations which customer bought a car, which made car listings that are in stock at any given time.
Exercise 2: College tuition
Get the conceptual model of a system that manages the enrollment of students in a university. A person is characterized by its CI, name, address and marital status, and it can become a student to register as such at the university.
As a student may enroll in the courses taught at the university, which will have a code, a name, a responsible teacher and a course assignment. Once enrolled, the student will receive a scholarship and in his new capacity as fellow will be assigned a new code and know the amount of the same, end the course, the scholar status will end. Once the student enrolls, whether you receive scholarship or not, should be examined in the subjects in which he is enrolled until the end of the course and then re-enroll or leave the university and this is still a student. In addition, it is desirable to have a range of applications such as discharge to new people and subjects, conducting student enrollment in courses, record the grades of students to examine any subject in which they are enrolled and a series of listings such as those enrolled in a subject, the subjects in which a student is enrolled and the list of notes by subjects (minutes).
class diagram also asked to identify the use case diagram concerned.
Exercise 3: Veterinary Clinic
A veterinarian has the animal patients and families as clients. A client is a group of people that usually correspond with a family. Each client has a code, the last name of head of household, bank account number, address, telephone and the names and CI of the persons concerned. There is no limit on the number of persons associated with a client entity. In addition, a person may be discharged on multiple clients (eg a man who lives with his wife has a cat and as such belongs to a client, but is registered in the client associated with the dog of your parents.)
Customers can have multiple pets, each pet has a code, an alias, a species, race, hair color, approximate date of birth, average weight of the animal in its last 10 visits and the actual weight of the animal. Also, keep a chart with each disease and the date was that sick. Additionally, each pet has a vaccination schedule, which will record the date of each vaccine and the disease are vaccinated.
Exercise 4: CD-ROMs Vacation
Is a company dedicated to rent audio CD-ROMs. This company has a local customer service which displays the covers of the most popular CDs and the latest developments, but there are paper listings of all titles that could be rented. When a client requests a certificate, copies of checks for free and if there are problems with individuals not returned the lease is done, there is a record of the date of hire and delivery deadline, so that when the customer returns the copy we can check if you have to impose a sanction. Each client can request a list of the CDs you have rented previously.
In addition to the class diagram, identify and propose the use case diagram associated with the proposed system, assume two actors: client and manager.
