CS3733-B04 Midterm Exam Name:_____________________________________________________________ This exam consists of two parts. If you have read the textbook, attended the lectures, done the homework, and studied the notes you are prepared. Remember that there is a code of academic honesty at WPI and you are expected to do your own work. Good luck. Part 1 (50 points) 1. Which of the following are the main parts of a software development process? a. People, tools, project b. Requirements, analysis, design, testing c. Roles, activities, artifacts d. Models, requirements, code 2. Which of the following is not a phase in the Rational Unified Process? a. Elaboration b. Continuation c. Inception d. Transition e. Construction 3. Using the appropriate FURPS letter, indicate which type of requirement the following are: a. ___U__ The system must conform to the individual platform handicapped accessibility standards. b. __P___ The compiler must compile a minimum of 5,000 tokens per second when running on a 2.0 <a href="/keyword/ghz-pentium/" >ghz pentium</a> 4 processor. c. ___F__ The system shall allow payment by cash, debit card, or credit card. d. __S___ The source code will contain no warnings when processed by the PMD static analysis tool. e. ___R__ The system must be accessible 24 hours a day, 7 days a week. 4. Jacobson identifies three types of analysis classes. What are they? Entity, Boundary, Control Gary Pollice Page 1 <a href="/keyword/worcester-polytechnic/" >worcester polytechnic</a> Institute 4/8/2005 CS3733-B04 Midterm Exam 5. Describe in a sentence or two how an iterative, incremental process model helps manage change. During each iteration, you completely implement only a part of the system before reviewing the work. This ensures that you do not stray too far from what is needed at any given time. Also, you perform requirements management and reflect on the process during each iteration so that you are forced to adapt to changes as quickly as possible. 6. What is a use case? A use case is a complete sequence of events, initiated by an actor, that delivers visible results. 7. What is the difference between a use case, a flow of events, and a scenario? A use case is a complete description. It is made up on different flows of events. A scenario is one complete path through a use case that may involve several flows of events. 8. Which of the following would you use on your project to schedule tasks for programmers? a. Use cases b. Requirements c. User stories d. All of the above 9. What are two benefits realized by using Test-First Programming? Full code coverage. No code written unless you need it. Code is written to make the test work, rather than tests written to reflect the code. Tests are written to reflect requirements. 10. HBP, a major computer technology supplier, has just released a new technology for identifying security intrusions in programs. The technology has not been widely deployed because it must be implemented using the XLS language that is provided only by HBP. Your client wants to add the technology to an existing software system. Identify two risks that you must address early in the project. New language that the team must learn can make estimates very inaccurate. The technology has not yet been proven. It is possible that it will not work as you expect and you will have to find an alternate way of addressing the needs. HBP could go out of business, leaving you with an unsupportable product. Part 2 (50 points) Do one of the following problems. 1. You are working on a system to allow students to order pizza via the internet from their dorm rooms. They are able to connect to Mah Jong Pizza's local web site, place Gary Pollice Page 2 <a href="/keyword/worcester-polytechnic/" >worcester polytechnic</a> Institute 4/8/2005 CS3733-B04 Midterm Exam their order, and have the pizza delivered to their dorm in 30 minutes or less. Write the use case for ordering a pizza. Include a good name, brief description, and actors. Describe the main flow of events and at least one alternate flow. Identify any preconditions and post-conditions. After you have written your use case, draw the UML sequence diagram that illustrates the interaction of objects for ordering a single pizza successfully. 2. Perform a <a href="/keyword/textual-analysis/" >textual analysis</a> on the following and then draw a UML sequence diagram that illustrates the main flow of events, using the object that you've identified in your <a href="/keyword/textual-analysis/" >textual analysis</a> . Your <a href="/keyword/textual-analysis/" >textual analysis</a> should include each major class you discover and the main operations the class supports, based upon the text. Description During the course of a student group the students provide elaborations to the tutor. The tutor evaluates the elaborations and enters grades into the asse...
