First, the 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 suitable for describing the whole process of software design which is driven by use case and is architecture-centric. StarUML Use tutorial See http://blog.csdn.net/monkey_d_meng/article/details/5995610/ UML Model Diagram is composed of things, relations

1. Introduction to UML UML (Unified Modeling Language) is a visual modeling language that is well defined, easy to express, powerful, and universally applicable. It integrates new ideas, new methods, and new technologies in the software engineering field. Its scope is not limited to supporting object-oriented analysis and design, but also supporting the entire process of software development starting from requirement analysis. In the system analysis phase, we generally use UML to draw many diagr

The existence of UML time series diagramIn the previous article, the UML class diagram was recorded, and the class diagram was used to describe the classes needed in the code and the relationship between them, and the whole program framework was displayed in front of us, like a painting, there are some people with water in the mountains.A photo can only freeze at that time of the good, and so on, but often

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 used UML for projects I 've encountered before. I don't know if it's too late to learn them

Activity Chart: concept: an activity diagram is a flowchart used to describe the activities in the process and their transitions. element: contains elements of activity, State, transition, decision, and so on 1. Activity (Action): An activity in an activity diagram that represents the action of a work or a step that represents a workflow, represented by a rounded rectangle. In determining the name of the

Original: UML Use case diagram summaryReprint Please specify source: http://blog.csdn.net/tianhai110Use case diagrams are primarily used to describe the relationships between users, requirements, and system functional units. It shows a model diagram of a system function that an external user can observe."Purpose": helps the development team to understand the functional requirements of the system in a visual

Transferred from: http://www.360doc.com/content/10/1206/23/3123_75672033.shtmlSome time ago participated in the technical lecture of Pangayu teacher, UML modelling technology benefited greatly. I also put some of the usual accumulation and the last harvest summarized in this article, mainly on the use case diagram related knowledge.The use case diagram is the first step in the software requirements analysis

The study of the soft-work course has just ended, and the first version of our small online game development has been completed. The development documentation was also completed and the teacher was asked to review to give some advice.In the use Case Diagram section, we were previously divided into client and server use case diagrams, which were criticized by the teacher. Use case diagram is based on the cus

The package diagram and Use Cases Written in UML last time: connect to: UML from requirement to implementation --- package diagram According to the sequence of appearance in the UML diagram. After the package diagram is completed, the next step is the class diagram. The cla

The interaction diagram is used to describe how objects interact in the system, that is, how a group of objects transmit messages. Interaction is mainly used to describe the dynamic behavior of collaboration. When modeling interactions, it usually includes objects (each object assumes a specific role), messages (each message represents the communication activity between objects, and cause certain actions ). The interaction

UML Class diagram: To understand the class diagram of the lines between the various classes, what the arrow means is enough to deal with day-to-day work and communication, and we should be able to match the meaning of the class diagram to the final code; With this knowledge, there is no problem with the design pattern structure

I. Introduction to the methodology1. Definition: It is a method of analyzing the various combinations of input by means of graphic method to design the test case, which is suitable for checking the various combinations of the input conditions of the program. 2. Background of the cause and Effect diagram method:The equivalence class partitioning method and the boundary value analysis method all focus on the input conditions, but do not take into accoun

This is a creation in Article, where the information may have evolved or changed. First, the conclusion is listed in the front: Golang performance can be very good, but some native package performance is likely to be retarded, such as RegExp and Encoding/json. If used in high performance requirements, we should optimize according to the actual situation. The use of ON-CPU/OFF-CPU flame diagram is a sharp weapon of program performance

Start learning the UML modeling language, starting with the use case diagram. Modeling Tools Select VisioThe use case diagram describes the system functions understood by the participants, the main elements being use cases and participants, and helping the development team to understand the functional requirements of the system in a visual way. At this time in the project initial, analysis of the user needs

I. Purpose It is used to describe the static structure of the system. In all UML diagrams, class diagrams are the most familiar to us. We may have seen them when we are not in contact with UML. Class diagram, as early as in vs2005, there is a small icon "View class diagram" under "solution Resource Manager", and it also supports "Forward" and "reverse" engineering. First, we define two classe
