to represent other information, such as comments and semantics of model elements. In addition, UML provides an extension mechanism that enables the UML language to adapt to a special method (or process) or expand to an organization or user. Classification of UML views:UML is used to describe a model. A model is used to describe the institutional or static features of a system, as well as behavior or dynamic features. Model the system architecture from different perspectives to form differen

AssociationThe plot is the same as the Sequence Graph in many aspects. Both are used to record the interaction of objects. However, the sequence chart is based on time, while the collaboration chart displays objects and their associations without emphasizing time. Collaborate graph display to eliminate InteractionInformation sequence. The difference between the two lies in this. Therefore, the relevant content of the sequence diagram is also applicabl

Martin Fowler in his book "UML Distilled:a Brief Guide to the Standard object Modeling Language, Third Edition" (UML Essence: Concise Reference of standard object Modeling language South (3rd edition)), there is such a paragraph: "If someone were to come," "a dark alley and say, ' Psst, Wanna, a UML diagram?

[Keyword] UML component Diagram The main purpose of a component diagram is to display the structural relationship between system components. In UML 1.1, a component represents an implementation project, such as a file and a runable program. Unfortunately, this is in conflict with the term component, which is more common and refers to something like a COM component. With the passage of time and the

Label:we need to consider the relationship between the data when we set up the database, in order to clarify the relationship between the data we need to do a uniform collation of the data. For the more complex database, we need to establish a database model, which can be divided into two steps: first, the structure analysis of the database and the use of tree, table and other descriptive data, and then analyze the database operation methods, rules and additions and deletions of the database ope

Objectiveclass diagrams and sequence diagrams are two of the most commonly used diagram in UML. I will make a detailed summary. In many books, or Web sites, when introducing the design of a subsystem of a system, many times, a simple class diagram is given to describe the relationship between the classes that make up the subsystem. This is sufficient to illustrate the importance of class diagrams. The basic

After reading the UML video, I want to start drawing documents. I don't know how to start! Let's summarize the nine types of diagrams and relationships in UML, and then start with the document. First. The nine types of UML diagrams are: use case diagram, class diagram, object diagram, state diagram, activity

UML Dynamic Model diagram describes various aspects of system dynamic behavior, including use case diagram, sequence diagram, collaboration diagram, activity diagram and state diagram. Here is a brief description of each diagram:u

UML defines the following 5 categories, 10 model diagrams. The first class is the use case diagram, the use case diagram describes the function of the system from the user's point of view, and points out the operator of each function. The second category is static diagrams, including class diagrams, Object diagrams, and package diagrams. The class diagram is us

Come on, let's move on to the dynamic map. A, state diagram A statechart diagram is used primarily to describe the dynamic behavior of an object during its lifetime. In other words, the system has a state, then the action, the transformation into a different state. To give a chestnut, the user is in the machine state, click the next Machine button, into the machine state. Of course, there may be insuffici

aggregation. In addition, each wild goose has two wings. The relationship between the wild geese and the wild geese is called combination. it can be seen that the relationship of aggregation is obviously not closely formed. The geese cannot survive because their Group Owners disband the geese, and the geese cannot survive independently because they have the same life cycle. Aggregation relationship diagram: Combination relationship

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

Abstract: this is an article about the unified modeling language, that is, the basic diagram used in UML. In this article, I will discuss the structure diagram, which is a new graph type that has been proposed in UML 2. Since the purpose of this series of articles is to help people understand the mark elements and their meanings, this article mainly involves class diagrams. You will soon know the reason for
