Vital objective of this lecture is to explain Analysis Modeling. Analysis modeling uses a variety of text and diagrammatic sorts to depict prerequisites for data, purpose, and behavior in a way that is relatively clear to see, and more important, straightforward to assessment for correctness, completeness as well as consistency. Analysis modeling uses a variety of text and diagrams in order to represent software prerequisites (data, function and so on) in the understandable way. Building analysis models makes it easier to uncover requirement inconsistencies as well as omissions. Two varieties of analysis modeling can be used: structured evaluation and object-oriented evaluation.
