Component diagram, English name Yue: Component diagrams is used to describe the organization and dependencies between a set of artifacts, for the static implementation view of a modeling system, which can be executable programs, libraries, tables, files, and documents, and includes implementation information for logical classes or logical classes. Therefore, there is a mapping relationship between the structure model view and the implementation. Comp

I haven't studied UML for many days because of the exam, and I feel a little unfamiliar. So hurry up and make up for my inner emptiness. We have to take the test this afternoon, and there is still nearly two hours in the middle. Now I will share with you my understanding of the object diagrams in UML. Of course, I have concluded that I have never drawn any picture, in the future, we will add the picture in

Unified Modeling Language (UML) use case diagramThe use case diagram describes a functional unit provided by the system. The purpose of the use case diagram is to help the development team understand the functional requirements of the system in a visual manner, including the relationship between "Roles" based on the basic process, and the relationship between use

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

Reading videos or tool books, including summaries, is in the theoretical stage. "The last word on the paper is superficial. I know that this is a must ." Now we are in the UML document stage, and it won't work unless we do it. I have done the "Data Center Charging System" before. To put it bluntly, I am blind. I have no rules to follow the feeling. The training solution provides the following explanation: "

Class diagrams and sequence diagrams are directly associated with program code in software system design. To be precise, program code is directly generated by class diagrams, A Sequence Chart can define a class chart method. The use case diagram is used to describe system functions and has no direct relationship with t

This short article is well written. it can be said that using PHP to explain UML (or conversely) is an innovation. through this article, I also found a good site: www.phppatterns.com. I am reading the UML User Guide (TheUnifiedModelingLanguageUserGuide) Synt. This short article is well written. it can be said that using PHP to explain UML (or conversely) is an in

SummaryThis article briefly analyzes and designs an example of a "Student Course Selection System" to illustrate the two functions and forms of a class diagram in a UML diagram, in order to clarify the misunderstandings and confusions that some friends may have on class diag

Class) Class (FigureIs an object blueprint, which contains three components. The first is the class name defined in Java. The second is attributes ). The third is the method provided by this class. You can append a visibility modifier before attributes and operations. The plus sign (+) indicates public visibility. Min

Sequence diagrams are primarily used to show the order in which objects interact with each other.A sequence diagram represents an interaction as a two-dimensional graph. The vertical is the timeline, and the time extends downward along the vertical bar. The horizontal axis represents the meta roles of individual objects in collaboration. The class meta role is represented by a lifeline. When an object is pr

Class diagram is used to describe the classes contained in the system and the relationship between them, to help people simplify the understanding of the system, it is an important product of the system analysis and design phase, but also the system coding and testing important model basis. Let's talk about the composition of the class

, including requirements analysis to specification, to construction and configuration. Different organizations of different software on the classification of UML is different, basic all the UML software contains the following 4 major categories1. Use case diagram2. Class Diagram3. Activity diagram4. Sequence diagram

multiple links1Written by one party1, Write by multiple partiesN; Multiple-to-many relationships are written in the direction of the two physical connections.N, m UML: The first use case diagram (Use Case digoal) The second type is static digraphs, including class graphs, object graphs, and packet graphs. The third type is the behavior

This essay is good, the use of PHP to explain the UML (or conversely) can be said to be an innovation, through this article, I also found a good station: www.phppatterns.com. The translation of the UML terms comes from the Unified Modeling Language User Guide, which I am looking at. UML (Unified Modeling Language, Unified Modeling Language) is a mechanism for re

use case diagram. composition: System boundaries. Participants. Case. Relationship. Participant: Actor is not a person, but a role to play when participating in a use case. If the action of one role is done by another role agent, establish a dependency between the role and the other role. How to identify the participants. who is providing information to the system? Who gets information from the system. Who operating system. What external resource sy

. For this long square lattice, I have never understood what it actually means. I encountered an open-minded explanation on "Baidu Encyclopedia:You can think of activation as a "{}",From the beginning to the end, it can be understood as a method, an action; The lifeline is used to describe the time when an object exists. Add the destroy symbol below to delete the object or recycle the object. It is actually a Roman's dragon nest. When it's done, let's leave. There are four types of messages, but

At the beginning of the painting is really tangled, at that time was forced to draw under the master, but it is also good, in the strong request of master, I learned how to use the EA, but also for a learning a new software has a better way to find some video, or text materials to help us learn to use the new software.Each time the drawing has a new understanding, after this and the regulation of the consolidation of software requirements have a deeper understanding, we have so many layers is to

Preface In Ooa and Ood, UML has been widely used in system analysis and design. In UML's 9 kinds of graphs, the class diagram is one of the most important and most commonly used graphs. However, in the chat with some friends, especially beginners, I found that many friends have some misunderstandings and puzzles about the function and the method of using the
