UML: Unified Modeling Language Unified Modeling Language (UML) is a language used to describe, construct, visualize, and compile software-intensive systems. First, it is also the most important thing. The Unified Modeling Language integrates the concepts in booch, OMT, and OOSE methods, it is a simple, consistent, and universal modeling language that can be widely used by users of the above and other method

In the first part, we have established the understanding that UML is a language used to develop the components of software systems and the standard of interactive methods. UML involves 6 major aspects-from use-case models, dynamic and logical models, to final physical deployment models, and extension mechanisms that allow special annotations to be added to models.So, how do you use

　　When I mentioned UML before, I thought of the complicated flowchart. I admire the people who think about the UML diagram of the whole system, because they have the blueprint of the whole software architecture in their mind, so that when writing the implementation, they will know where to change and where to expand. And to be an architect, UML is also an ess

Classes may have the following relationships: Association, dependency, aggregation, aggregation, composition, and generalization, also known as inheritance), implementation (realization ). 1: Association refers to the relationship between two classes. For example, a customer and an order can only belong to one customer. A customer may have multiple orders. It can be divided into one-way and two-way directions. It can be divided into one-to-one, one-to-multiple, and many-to-many based on the corr
