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.
What are the benefits of horizontal partitioning? i. Software that is simple to test. ii. Software that is simpler to maintain. iii. Propagation of fewer side effects.
Define the concept of SRS An SRS clearly defines following: • External Interfaces of the system: They identify information which is to flow 'from and to' to the system.
Write definition of DFD? Data Flow Diagram supplies the information flow and the transforms that are used on the data as it moves from input to output.
Glass box testing is the similar as white box testing. It's a testing approach that consider the application's program structure, and derives test cases from the application's prog
what is software decomposition? what are its techniques?
Grey box testing is a software testing method that uses a combination of black box testing and white box testing. Gray box testing is not the black box testing, because the tester
Describe Equivalence Partitioning Ans) Input data of a program is separated into different categories so that test cases can be developed for every category of input data. The g
What is Equivalence Partitioning? Equivalence Partitioning (EP) is the process of methodically decreasing the huge set of possible test cases into a much smaller but still equ
Explain in detail about Functional Modelling. This model explains the computations that take place within a system. This model is useful when the transformation from t
