Object-oriented analysis model includes function model, analysis object model and dynamic model. The analysis class can be divided into entity class, boundary class and control class 3 types according to the behavior of the object in the system according to its effect and change.
Boundary class: A boundary class that corresponds to an interaction or communication association between a participant and a use case.
Control class: Responsible for coordinating boundary classes and entity classes, receiving boundary classes and distributing them to entity classes.
Entity class: Is the participation object in the use case, corresponding to the reality.
Building a sequence diagram can link use cases and analytic objects together. After analyzing the interaction behavior, the analysis class diagram can be established to express the relationship between the analysis classes more clearly and intuitively.
