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

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

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

trufun Plato UML2 modeling toolTrufun Plato is a new generation of UML modeling software that provides efficient and fast modeling tools for your software analysis design.Trufun is a case tool manufacturer that synchronizes the release of uml2.x tools after the OMG release of the UML2.2 specification, and is a state-of-the-art, Enterprise-class UML tool based on

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

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 "

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

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

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

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

The idea of the merge development platform: If the activity diagram can run, then the development process of the business logic is approximate to the drawing process.Developed for Merge1.0 scripting:650) this.width=650; "Src=" Http://s3.51cto.com/wyfs02/M01/89/46/wKioL1gOoRSxPhHjAAG0iwYg2Dg758.png-wh_500x0-wm_3 -wmp_4-s_1413011658.png "title=" P1.png "alt=" Wkiol1goorsxphhjaag0iwyg2dg758.png-wh_50 "/>Models include:Base part: Start, variable assignmen

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

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 most common relationship between classes and classes, and it is a structured relationship that indicates that a class of objects is associated with another class of objects, such as classes and students. In a UML class diagram, a cl
