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, what is UML UML class diagrams can quickly examine code structures. 2. Theme The use of UML class diagrams in Pycharm. 3. Preparation work (1) Pycharm version is 2.7 or higher (2) Installing the Python Interpreter (3) UML Plug-ins and UML class diagram plug-in installation and normal use 4. Prepare an example Create a Animals module and mammal.py file (Alt+insert→python Package, Python file) and enter the following code: Continue to add more class

One: Dynamic View---> Dynamic view is a description of the dynamic behavior of things. ---> Note that a dynamic view cannot exist independently, it must refer to a static view of a live uml element, explaining their dynamic behavior under the structure of things defined by static views. ---> Dynamic view: Activity diagram, state diagram, timing diagram, collabora

Class Diagram: Commonly used to analyze business concepts Use case Diagram: Common Object

The object class diagram of UML can be better usedDatabaseModeling. Traditional E-R diagram only focus on data, while UML object class diagram not only on the data, but also on the behavior modeling, these behavior in the physical database is designed as a trigger and storageProcess. For relational databasesSystemYou can use an object class

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

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

Additional questions: Deployment diagramKey concepts:1. The deployment diagram shows how specific software artifacts, such as executables, are assigned to a compute node (something that has a processing service). The deployment diagram represents the deployment of the software elements on the physical architecture , as well as the communication between the physical elements (usually over the network).2. The

10. Status machine diagram state machines diagramA state machine diagram is a common technique for describing a system's behavior. In an object-oriented approach, a state machine diagram is drawn for a single class to demonstrate the life cycle behavior of a single object.See Figure 10.1The diagram shows a state machin

I think the correct sequence of Data Center reconstruction is: database, drawing (package diagram, class diagram, timing diagram), and the implementation of code at the end of the document. However, although I think so, I did not fully follow this process. In my opinion, the Plan and sequence are dead, and people are living. What if you do not go down after a cer
