continue today to see the diagrams in the UML basic building blocks. a diagram of a UML basic building block A diagram of a UML basic building block is an abstract description of the system in a specific perspective. A graph is the classification of a collection of things, and UML contains many diagrams. Let's look at

Summary :-- recommended reasons : Recently from the Windows operating system to the MAC, is looking at design patterns and refactoring, can not find good UML tools, so on the internet to find an online use of the UML tools, used to find it well, recommend to everyone;-- tool address : https://www.processon.com/;I.

Basic concepts of UML [dependency, association, generalization, implementation] and basic concepts of umlI. concept: Introduction to the basic concepts of UML: UML: UML (Unified Modeling Language) provides a Unified, standard, and visual Modeling Language for Object-Oriented software design. It is applicable to the who

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

Easy introduction to UML (3)-SRP cook well, let others program, uml-srpA cook can make a good dish. Maybe he graduated from New Oriental or the secret recipe of his family. It is simple, happy, and efficient for you to let him cook a table of food. However, programming will become an annoyance and hard nut to crack. Maybe this metaphor is not very appropriate, but for every class, they are like an actor, ma

Three main elements of modeling: 1. Basic Construction blocks of UML; 2. Rules on how to put these constructor blocks together; 3. Some common mechanisms applied to the entire UML; The UML constructor consists of three types: A, thing B, relationship C, and diagram. Things: including "structured things", "behavior things", "grouping things", and "commenting thing

Not many computer players have not learned much, but with the continuous development of the project, those who have never seen before, and those who have never used them are all about to start learning. Although I have heard of UML for a long time, I have never read this book and have never used this tool. The class diagrams of UML are also unknown. Basically, I don't know how to understand it. I haven't us

Author: zyl910I. background Currently, many commonly used UML tools do not support objective-C, which is inconvenient to draw UML. You must manually convert the objective-C syntax parameter list to the UML or C ++ syntax. It is laborious and error-prone.So I want to write a tool that automatically converts the parameter list of objective-C syntax to

There are many types of UML diagrams, only two of the most important and common-class and time series diagrams are discussed here. 1. Class Diagram through the class diagram, we can easily understand the code architecture, clarify the relationship between the modules, includes inheritance (inheritance), implementation (realization), dependency (dependency), composition (composition), Aggregation (Aggregation), Association (association), and so on. The

and design of object-oriented systemIn object-oriented technology, the process of building an entire software system is often referred to as object-oriented analysis and design (object-oriented analyze and Design,ooad). For the software system we are developing, Ooad solves what the system is (object-oriented system analysis, i.e., OOA) and how to do it (object-oriented system design, or Ood), and OOP simp

If the elements in UML are basic words, the view is the syntax. Sort out the views in UML: Static View: As the name implies, a static view is a view that expresses static things. It only describes the static structure of a thing and its dynamic behavior. Examples, class charts, and package charts are provided. Use Case Diagram: Use Case Diagram is the first step from software requirement analysis to fina
