Software Analysis

Software analyses are dividing into five parts:
Objectives of analysis model
  • To describe what the customer require.
  • To establish a basis for the creation of a software design.
  • To define a set of requirements that can be validated once the software is built

    What is a model?
    Ans:a model is a simplification of reality

    Why do we model?
    -we build models so that we can better understand the system we are developing.
    -we build models of complex systems because we cannot comprehend such a system in its entirety.
    -four aims to achieve:-
    1. help us to visualize a system.
    2. permit us to specify the structure/behavior of a system.
    3. give us a template that guides us in constructing systems.
    4.document the decisions we have made.
