It is unified modeling Language, a modeling language that is a powerful tool for requirements analysis and outline design. In your understanding, what is UML? Is it just a collection of graphics, text, and symbols? Or

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

graduated from New Oriental will go to Sichuan cuisine. Then we will say that we will use interfaces instead of inheritance here. If we put the cooks and programmers together, they are all persons. Here we will use inheritance instead of interfaces. Here we forget the unlucky Cook first. We first define a Student class which has three methods: read (), dance (), and sing:However, we found that although every student could read books, not all of them could dance, and some of them were still inco

Object-Oriented Software Engineering and UML, software engineering uml Basic concepts of Software Engineering Software Crisis The functions, scale, and complexity of a software increase, and the complexity of the software reaches the level that cannot be controlled by its developers. This situation leads to serious consequences: Software Reliability reduction, low development efficiency, and extremely diffi

plantuml--Simple and fast UML editing software for EclipseIntroduction: in the application system software development process, if the software is composed of many objects, its structure is difficult to clarify by virtue of analysis, at the same time in order to facilitate the development and reuse of software, so in the development of the system before the modeling is very necessary, in a number of modeling methods to choose one to adapt to their own

UML is a general modeling language, its expressive ability is quite strong, not only can be used in software system modeling, but also can be used for business modeling and other non-software system modeling. UML synthesizes The advantages of various object-oriented methods and representations, and has received extensive attention and support from the industry since the date of presentation. This chapte
