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

statements at the common layer once. If you do not need the common layer and the same SQL statements are used more frequently, You need to modify each statement at the time of modification, it is prone to errors. Layer B is a logical combination of methods in layer D classes to complete a function. It can be said that a specific use case requires a class or method in layer B. Of course, sometimes layer B does not need layer D. The time sequence

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

Objective 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

Because the actual results of the previous solution were not satisfactory and did not match the initial project reported to the teacher, I switched to the original idea here to continue the game. We still plan to use the unity engine for development, but due to the characteristics of one stroke, this finished product should be a 2D horizontal version of the platform to solve the puzzle class game, the following project is the demand and

(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 () [UML diagram]

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 "

In the nine diagrams of UML, the class and object graph are static graphs, and the reaction is the static process of the system. The class diagram is described earlier, and the following is the object graph. One, the object graph summary Two: Object Graph example The object graph is concrete, and the

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

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

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,

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

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

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

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

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

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

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
