Transcription

1 QUESTION BANK UNIT 1 1. Explain how systems are modeled from different viewpoints. (10 Marks) Dec12 2. Elaborate on the major themes that are well supported in object oriented technology. Dec 12 (10 Marks) 3. Using class diagram prepare and object diagram for two triangles with a common side under the following conditions. Dec 07 / jan 8 (10 Marks) (a) A point belongs to exactly one polygon (b) A point belongs to exactly one or more polygon 4. Prepare a class diagram for each group of classes. Add at least 10 relationships (associations and generalizations) to each diagram. Use association names and association end names where needed. Also use qualified associations and show multiplicity. You do not need to show attributes or operation s. As you prepare the diagrams, you may add classes. Be sure to explain your diagrams. Automobile, engine, wheel, brake light, door, battery, muffler, tail pipe. Dec 07 / jan 8 (10 Marks) 5. Wire is used in the following applications. For each application, prepare a list of wire characteristics that are relevant and explain why each is important for the application. Dec 07 / jan 8 (8 m) 6. Explain briefly the following object orientation themes with suitable examples jun 08 8m 7. List the three kinds of models used in OOMD to describe a system. jun 08 8m 8.

Discuss Sequence diagram basic and advanced with diagram 10 marks Jan When a software system uses servers distributed over a network it must provide a means for communication between them. Clients should not need to know where servers are located. To solve this which pattern is used and explain the dynamics and implementation of the pattern.
