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 r

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.

Understanding the JVM virtual Machine principle is a necessary step for every Java programmer to practice. But because there are a lot of things in the JVM virtual machine to tell the relatively broad, in the current exposure to the JVM virtual machine principle of the tutorial or blog, the vast majority of the text-based description, it is difficult to give people a visual perception, after reading the feeling is still confused. Feeling the above, I

In my study of design patterns, I used UML for modeling.At first I was not too clear on the understanding of the various relations, on the internet also searched some information, now on the class diagram of these kinds of relationships: dependency, association, aggregation, composition, generalization, implementation of a description.First of all, we need to kno

combination.Example of creating a draw2d Image Is a simple UML class diagram. This article is based on the creation of this graphic.Design graphics The first step in creating a graph is to determine what components are used to synthesize the graph and how they are arranged. An example graph consists of three subgraphs. The image itself is umlclassfigure, its fi

functionally equal, the second arrangement is more neat. Figure 1. "messy" DiagramFigure 2. "clean" Avoid boxes of different sizesHow can we improve Figure 1? First, make sure all the boxes are of the same size. A large box seems to be more important than a small box. If this is what you try to express, that's right-but if I select it, I 'd rather keep all the boxes in the same size. This method is most suitable for the "UML use case"

The direction of the arrow pointing to the edge indicates the direction of the message being passed, what message is identified above the forward edge, the time sequence in which the message is sent, and the number appended to each message, and it is clear that the collaboration diagram makes it easy to describe the collaboration between objects. There is no need for a sequence

. "When" is the answer, that is, how the development work is scheduled; 4. "Who" means that some development (or maintenance) work is intended to be done by "who? "· 5. "How" means how certain requirements are met; 6. Why? The above is the relevant content of the soft work document. Let's take a look at the relationship between the UML diagram and the document below: First, the

The name of the model package is a string that can be divided into simple names and path names .Simple name: refers to a package that contains only a simple name.pathname : Refers to the name of the outer package that the package is located in as a prefix.3, the role of package diagrams:Package diagrams can describe the requirements, the design of the high-level overview, package diagram through the rational
