CS 3802 - Introduction to Software Engineering

Samples Midterm - Spring Quarter 1999

Instructions: The time for the test is 1 hour and 25 minutes. All the answers are to be written on this paper. One of the secrets to success on this exam is to be concise and neat; the other is to be sure to ask for clarification if you think you need it. The test is closed book and closed notes, but open mind.

1. (5 points) What is Software Engineering?
 

2. (5 points) Explain the difference between functional and non-functional requirements.
 

3. (5 points) The IEEE classifies bugs into two categories: faults and failures. Define these terms and give an example of each.
 

4. (5 points) Software project planning, including both time and cost estimation, has historically been a very difficult and inaccurate activity. Give five (5) reasons why.
 

5. (5 points) Do you agree with the following statement? Why or why not?
"A general statement of objectives is sufficient to begin writing programs ó we can fill in the details later."
 

6. (5 points) Define coupling and cohesion, and explain their significance in the software design process.
 

7. (10 points) Describe the processes involved in a complete software lifecycle.
 

8. (10 points) Describe the five (5) major roles of the members of a software development team.
 

9. (10 points) Compare and contrast the Waterfall and Spiral models of the software lifecycle.
 

10. (10 points) Compare and contrast Structured and Object-Oriented Requirements Analysis. Explain the advantages and disadvantages of each method.
 

11. (15 points) Draw an object model for the following system. Be sure to state any assumptions that you make.

"Zoo Atlanta needs a new database to categorize its animals, and to keep information about them. Animals are identified by genus and species, and individual animal names. For each species of animal, the zoo keeps information about diet, environment, and sleep habits. Records are kept for individual animals that include location of the animal, medications given, and special dietary restrictions. There is also a zookeeper database listing all of the zoo's personnel, including their names, addresses, and areas of specialization. Each animal in the zoo has a primary zookeeper assigned to its care."

 

12. (15 points) Remember the microwave oven that we analyzed in class. As you recall, it was a pretty dumb oven. This time draw a machine diagram for a "real" microwave oven. It should have, at minimum, the following: (Bonus points may be earned by increasing the complexity of your microwave beyond the standards listed below.)
