Understanding Dynamic ModelingAll object-oriented design should represent the structural and behavioral aspects of a software system Static modeling i Hiểu biết về mô hình hóa động is used to represent the structural constituents of a software system. Dynamic modeling is used to represent the behavior of the structural constituents. Dynamic modeling uses various types of diagrams, such as interaction, state, and activity diagrams.This chapter explains the concept of dynamic mo Hiểu biết về mô hình hóa động deling. In addition, it explains how to create the dynamic model of a system by using interaction diagrams.ObjectivesIn this chapter, you will learn tHiểu biết về mô hình hóa động

Without a good design a developer will not be able to code a program correctly. This is because coding involves the implementation of the design.MHiểu biết về mô hình hóa động

It provides various diagrams such as, interaction, activity, and state diagrams, which help you design the dynamic model of a software systemConsider the example of Wilson Inc., an au Hiểu biết về mô hình hóa động tomobile manufacturing company, which is planning expansion and, for this reason, wants to automate Its inventory control.

The dynamic model of the IMS is created using various diagrams, such as interaction, state, and activity diagramsThe interaction diagram models the interaction between the static constituents of a software system. The activity diagrams represent the Hiểu biết về mô hình hóa động sequence of activities that the static constituents of a system need to perform to complete a process and the state diagrams depict the changes thatHiểu biết về mô hình hóa động

To depict the behavior of the structural constituents, you need dynamic modeling.
