From: http://www.yesky.com/SoftChannel/72342393403211776/20040506/1794427.shtml The UML activity diagram records the logic of a single operation or method, a single user case, or a single business flow. To create a UML activity diagram, perform the following steps repeatedly. Step 1: define the scope of the activit

I,Description of the use case diagram Use Case (Use Case) Refers to the interaction between the system's external things (activists, devices, or external systems) and the system. It expresses the functions of the system, that is, the services provided by the system. A Use Case chart is a visualization tool used to describe use cases. It uses simple graphical elements to represent the system's activists, use cases, and their relationships, accurate

UML has the following diagram: Use case diagram, class diagram, sequence diagram, collaboration diagram, state diagram, activity diagram, c

without an arrow, an arrow pointing to a use case, and an arrow pointing to a role. No matter whether there are arrows or not, these lines are used to connect roles (villains) and use cases (circles), indicating what use cases a role can "do.A line with arrows indicates the flow of data during the interaction between the role and the system. If the arrow points to a use case, the role needs to input data to the system. If the arrow points to the role, the system outputs data to the role.The lin

artifacts must be on the nodes that correspond, rather than being isolated. iv. Explanation of the deployment diagram(1) Node: the common name of the compute resource. Includes processors and devices. Where the processor is the hardware structure that can execute the program, such as computers and servers. A device is a service that is performed externally through an interface, such as a printer. Each node should give the appropriate tag description,

Currently the more popular UML modeling tools include Visio, Rational Rose, PowerDesigner, EA, and so on, basically enterprise-class software, powerful, I have only used Visio, so do not add to their characteristics or similarities and differences. For more formal scenarios, such as graphics as part of a project document, the software listed above is recommended. When we encounter more complex code logic or business logic at work, it is easier to unde

understanding of collaboration diagrams, figuring out what the collaboration diagram is capable of, and being able to be an invincible position in the great family of UML, let's take a look at the components of the collaboration diagram and the steps to create a collaboration diagram: Through the previous study we

The UML activity diagram records the logic of a single operation or method, a single user case, or a single business flow. To create a UML activity diagram, you must perform the following steps repeatedly to modify the sixth chapter of the object entry level 2. Step 1: define the range of the activity

Preface I have been using PHP for more than two years. I have prepared and written some frequently-used design patterns based on my own practical experience. before using the design patterns, I must first understand the design patterns, therefore, we will first explain the UML class diagram. Through UML class diagrams, you can better communicate with everyone and

Ref (Reference) Used to point to an interactive situation as defined in another diagram. We'll make it a box that covers the lifeline of th

The UML class diagram is the basis for learning the design pattern. Through the UML class diagram, you can better communicate with everyone and easily express your own design ideas. It is like Mandarin, is a standard language. Currently, there are two popular tools: Rational Rose and Microsoft Visio, both of which are

the dependent package. Note: The package marked with {Global} is a universal package, indicating that all other packages in the system depend on this package. Generalization: express the general and special relationships between things. If there is a general relationship between the two packages, it means that the special packages must follow the interface of the general package. {Abstract} indicates that it defines an Interface 10. Use the

Case modeling is a part of UML modeling and the most basic part of UML. The main function of case modeling is to express the functional requirements or behaviors of the system. To put it bluntly, it is to explain what the system is, so you don't have to worry about how to work. I think the use case chart is the best picture in the analysis phase, because the content is very macro. Understand the elemen

Activity diagram, her English name is active Diagram, a workflow that describes the implementation of a business use case, which is one of the none of the diagrams used in the UML family to model dynamic aspects of the system. To give a simple example, to build a work flow for example, first of all, we have to select an address, and then commissioned an architec
