The editor will share with you the example analysis of UML object-oriented technology. I hope you will get something after reading this article. Let's discuss it together.

Brief introduction of UML object-oriented Technology

Object-oriented technology emphasizes facing the things in the objective world or problem domain in the process of software development, and adopts the thinking method commonly used by human beings in the process of understanding the objective world to describe the related things in the objective world intuitively and naturally. The basic characteristics of object-oriented technology are abstraction, encapsulation, inheritance and polymorphism.

Object-oriented Analysis and Design process based on UML

1) identify the use cases and roles of the system

First of all, carry on the requirement investigation to the project, according to the business flow chart and data flow chart of the project and the operators at all levels involved in the project, through analysis, identify all the use cases and roles in the system; then analyze the relationship between the roles and use cases in the system, and then use UML modeling tools to draw the use case diagram of the system, at the same time, outline the concept layer model of the system, and describe the concept layer class diagram and activity diagram with the help of UML modeling tools.

2) analyze the system and abstract the class

The task of system analysis is to find out and describe all the requirements in the system, and establish a specific domain model at the same time. The establishment of a domain model helps developers to examine use cases, extract classes from them, and describe the relationships between classes.

3) Design the system and the classes in the system and their behavior

The design stage consists of structural design and detailed design.

① architecture design is a high-level design, its task is to define packages (subsystems), including the dependency between packages and the main communication mechanisms. Packages help to describe the logical components of the system and the dependencies between them.

The detailed design of ② is to refine the contents of the package, clearly describe all classes, and use UML's dynamic model to describe the behavior of instances of these classes in a specific environment.
