5. Explain with example diagram the functional and behavioral modeling. How do we model the software’s reaction to some external event? 6. State and explain the requirements engineering tasks in detail. 7. Describe the primary differences between structured analyses and object oriented analysis. 8. Write a detailed note on scenario based modeling. 9. Why is traceability an important aspect of requirements management? Why context system models are useful for requirement validation? 10. Describe how Software requirements are documented? State the importance of documentation .

CS8494 SOFTWARE ENGINEERING Question Bank 2017 Regulation Page 10 UNIT: III - SOFTWARE DESIGN PART A 1. List two principles of good design. (Nov/Dec2013) Models should be easily understandable Both internal and external interfaces should be designed with care. 2. Define interface analysis. Interface analysis is to understand the problem before attempting to deign a solution. It means understanding People Tasks Content Environment 3. Define architectural mapping using data flow. A mapping technique called structural design is characterized as a data flow oriented design method because it provides a convenient transition from a data flow diagram to software architecture. 4. Define Software Quality. (Nov/Dec2013) Software quality is defined as the degree to which software meets customer requirements. 5. What are the types of prototype? (Nov/Dec2013) Built-in prototype Throw away prototype 6. Distinguish verification and validation. (May/June 2014) (April/May2011) (Nov/Dec 2010) S.No Verification Validation 1 The set of activities that ensure that software correctly implements a specific funaction. The set of activities that ensure that the software has been built is traceable to customer requirements. 2 Verification represents the set of activities that are carried out to confirm that the software correctly implements the specific functionality. Validation represents the set of activities that ensure that the software that has been built is satisfying the customer requirements. 7. Define Component Level design.

CS8494 SOFTWARE ENGINEERING Question Bank 2017 Regulation Page 11 A component is a modular building block for computer software. Unified Modeling Language (UML) defines a component as a modular, deployable and replaceable part of a system that encapsulates implementation and exposes a set of interfaces. 8. Distinguish fan-in and fan-out. (Nov/Dec 2011) Fan-out means number of immediate sub-ordinates to the module. Fan-out means number of immediate ancestors the modules have. 9. What is Cyclomatic Complexity? (May/June 2014) Cyclomatic complexity is software metric that provides a quantitative measure of the logical complexity of the program.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
