Explain the prototyping approaches in software process.
Two approaches
i. Evolutionary prototyping - In this approach of system development, the initial prototype is prepared and it is then refined by number of stages to final stage.
ii. Throw-away prototyping - Using this approach a rough practical executionof the system is produced. The requirement problems can be identified from this execution. It is then discarded. System is then developed using some disimilar engineering paradigm.
Q. Differentiate between functional testing and structural testing. Ans: Functional testing signifies behavioural testing or Black box testing. In this techniques the teste

Explain in detail about Black box testing. Black box or behavioural testing focuses on the functional needs of the software. It is applied during the last stage of testing.
List the principles of a software design. i. The design process should not suffer from "tunnel vision". ii. The design should be traceable to the analysis model. iii. The
