I believe everyone knows the full name of UML. Unified Modeling Language (UML is the abbreviation of Unified Modeling Language) is a language used for visual modeling of software systems. UML is a standard language for specifying, visualizing, and documenting products of object-oriented development systems.
I want to ask you two questions:
1. What is a model? A model is an abstract simulation and simplification of the shape or state of the real world.
2. Why model? The simplest reason: To be able to better understand the system under development. Through modeling, four purposes can be achieved:
1. Contribute to the visual analysis of the system according to the requirements
2. Enable the structure or behavior of the system
3. Provide a template for knowing how to construct the system
4. Document the decisions made
This article mainly introduces the seven views of UML. The so-called picture is worth a thousand words. We will use pictures to introduce the views of UML:
the first picture: an overall impact, seven views of UML.
Chapter 2 Figures; explains each view in detail.
Each of the seven views of UML has its own characteristics, and each has its own role. Only by correctly understanding the seven kinds of views can the nine kinds of UML diagrams be studied in more detail and in-depth. The nine diagrams of UML are the concrete manifestations of the seven views. The next article will focus on the nine types of UML diagrams, thank you for your timely attention.
