This article begins with a discussion of code-level issues. The main feature of Markdown is the design implementation.This article begins with the markdown perimeter code:UML sequence diagrams are obtained from https://github.com/bramp/js-sequence-diagrams copy.When this UML code also uses two JS, function library and drawing.First of all, talk about this JS core class:Https://github.com/bramp/js-sequence-diagrams/blob/master/src/sequence-diagram.jsFi
Package diagrams is a combination of model elements that are represented in UML in a notation similar to a folder, each element in the system can be owned by only one package, one package can be nested in another, and a package diagram can be used to classify the related elements into a system that contains a package, chart, or individual element. In simple terms, we can directly understand the package as a

UML is used to describe the entire design process of the system, and for this process produced a UML9 diagram: Use case diagram, Class diagram, object graph, collaboration diagram, sequence

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.

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 activity diagram. First, define the modeling
definition of sequence diagram:
Interaction is the behavior of a group of messages that interact with a set of objects that implement a goal in a specific context. Sequence diagram is a kind of interaction graph. A sequence diagram is a visual representation of the time order in which messages are routed between objects. Sequence diagrams describe the needs of u
(Dependency)
definition: for two relatively independent objects, when one object is responsible for constructing an instance of another object, or depending on the service of another object, the two objects are primarily dependencies.
performance: dependencies are expressed in
local variables ,
the parameters of methods , and calls to
static methods .
Example: If you're going to screw the screws, do you want to use (ie rely on) a screwdriver (screwdriver)
Summary of the following four relationships
1. Generalization
2. Aggregation
3. Dependency
4. Join
1. Generalization
Is the integration relationship between the parent class and the Child class.
[Specific performance]
Parent class instance = new subclass ()

When you use Microsoft Visio to draw a use case diagram today, you find that the include relationship is not found in the Visio UML use case, which is the "arrow" + "Finally, a workable solution was found:First: Open the UML Model diagram, software and database, Microsoft visio-> newThen select "
Green is a plug-in for Eclipse, an advanced and simple UML Class diagram tool that major students develop and use. It is the live round-tripping editor, so it's easy to generate Java code from a UML class
In the UML 9 kinds of diagram, the use case diagram is the more important one kind of diagram, it is the diagram which produces in the system analysis stage, from the function carries on the analysis to the system the model, has played the strategically advantageous position
Sequence diagramA sequence diagram is a form of an interaction diagram that shows the evolution of an object along a lifeline, and the interaction between objects over time is expressed as a message from the source lifeline to the target lifeline. The sequence diagram is a good indicator of how those objects communicate with other objects, what messages trigger t
Finally began to refactor, the machine room reconstruction can be said to be a very important at this stage of our small project, because it relates to our time to learn all kinds of knowledge; First we use the knowledge of the soft workers, to do the work of writing documents before development, followed by the UML diagram, and then the main development environment of our refactoring is VS, It involves the

Object-oriented dynamic modeling, four diagrams of behavior interaction between entities, State diagrams (Stage Diagram), Sequence diagrams (Sequence Diagram), activities (activity Diagram) in front of the blog, we have learned, Today we are going to study the collaboration diagram (Sequence
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
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.

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
