. Unified Modeling Language (UML) Just like building a tall building, we need to draw a building diagram to build a model. During the system analysis and design phase of software system development, we usually use modeling technology to build a model for the system. Many modeling technologies have emerged during the development of software engineering. In the end, IBM's Unified Modeling Language
Implement UML sequence diagram and uml Sequence This article begins to discuss issues at the code level. It mainly refers to the design and implementation of the markdown function.

software components that will run on their systems. Although the system administrator will not be able to identify physical devices or things from the graphBut they still welcome the component diagram because it provided earlier information about the component and its relationship (which promised the system administrator to easily plan the subsequent work ).SymbolCurrently, the component diagram Symbol Set makes it one of the lightest and easy-to-draw

However, you can also model asynchronous messages in the sequence diagram. An asynchronous message is similar to a synchronous method, but the line drawn by the message carries a single stick, as shown in figure 6.Figure 6: sequence diagram fragment of asynchronous messages passed to entity 2ConstraintsWhen modeling the
as it is started. It seems that this design can help you get started quickly, but such a wizard will often confuse new users, this is the first question of these wizard! The second problem is that the wizard displays various templates and uses these templates to create a series of content frameworks that will make you dizzy. The third problem is: in actual work, these templates are basically useless. I don't like the content frameworks created by these templates. I will basically delete all or

These two days have been on the Internet to find the code based on Eclipse has been able to export UML, found that the green
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

Data Center reconstruction (1) -- UML diagram, Data Center reconstruction -- uml diagram Finally, we started restructuring. Data Center reconstruction is a very important small project at this stage, because it involves all kinds of knowledge we learned during this time. First, we used the knowledge of softwares, write the document before development, and then use the U
is to describe a simple elevator model. One person can draw very complex and detailed class digoal and sequence digoal, the other has a poor grasp of digoal details, but on the other hand, the latter considers that the top and bottom layers of the elevator are different from the middle layers and cannot be described in the same class, who should I hire? It is certainly not a UML diagram that can be very be

Class diagram, object diagram, role diagram: I. Basic Graph categories in UML:In UML 2, there are two basic graph categories: structure diagram and behavior diagram. Each UML diagram belongs to the two diagrams. The purpose of the structure diagram is to display the static structure of the modeling system. They include classes, components, and (or) object graphs. On the other hand, the behavior chart shows

a thing in the UML Some of the basic graphic symbols that make up the model diagram, which represent some basic object-oriented concepts.There are four kinds of things in UML structural things (structural things), behavioral things (behavioral things), group things (grouping things),Annotational Things (note things).

, and association relationships, can be nested, can have instances, and can participate in interaction.But there is a clear difference between them: artifacts are the things that participate in the execution of the system , and nodes are the things that perform the components , the components represent the physical packaging of the logical elements , and the nodes represent the physical deployment of the components .Draw points:Specific method: http:/
Four types of relationships in UML and four types of UML 1. Association Description: Assocition: Describes the structural relationship between two or more classes. (1) Common Association: 1) Association name: used to describe the nature of the link. 2) Role: When a class is at one end of the Association, the class plays a specific Role in the relationship; A role is the responsibility of a class close to on
