1. Sequence diagram (Sequence Diagram) is used to display the relationships between objects, emphasizing the chronological order of messages between objects, and showing the interaction between objects. A sequence diagram is a table where display objects are arranged along the x-axis, and messages are arranged chronologically along the y-axis. Sequence diagrams m

Question: many male and female students like each other and now require the largest independent subset. Solution: As the question shows that this kind of relationship exists only between men and women, you can boldly split the diagram, because men must like women, however, women cannot have edges (like relationships ). Maximum Independent Subset = number of vertices-Maximum number of matching. Because it is a split-point

Intermediary mode analysis, structure diagram and basic code, mediation structure diagram codeZookeeper Definition: a mediation object is used to encapsulate a series of object interactions. The intermediary makes the objects do not need to be explicitly referenced to each other, so that the coupling is loose and the interaction between them can be changed independently.Applicability: The intermediary mode

A powerful UML auxiliary toolQuick sequence dimo-editorIt is specially used to draw sequence graphs. The key is free of charge. Advantages: The sequence digoal can be generated instantly by writing simple scripts. With the image export function (PNG, GIF, BMP, JPG, PDF, and other formats), and can adjust the image size, the image is also very clear. Can draw asynchronous operations and mark the lifeline of different threads with different colors. (You can create diagrams that mod

Use case diagram is used in the requirement Analysis stage, describes the functional requirements of a system to be developed, the use Case view emphasizes the function of the system, and is the first design view of the software development design process. It describes the user's snowball from the user's point of view, describing the function of the system, and pointing out the performer of each function and what functions the performer has completed.

I. Concept of database designDatabase design is the process of planning and structuring the relationship between the data entities in the database and the data entities.Two. Importance of database designIf a database does not have a good design, then after the database is complete his disadvantage is:1. Efficiency will be very low2 There are many problems when updating and retrieving data.On the contrary, a database has been well-planned, with good design, then his advantages are:1. The efficien

We use PS to draw color wheel map, color wheel map is color phase diagram, it fully displays the Hue ring 360 degrees of all colors, PS hue/saturation command according to the color wheel design, but in the hue/saturation command, you see not the color wheel, but the color wheel of another form-color bar, You can take the color bar and cut it off along the edge of the color wheel. Then expand the effect, through the color wheel map, you can clear the

the relationships between classes Inheritance Relationship An inheritance relationship is the most understandable relationship. The picture is like this. The object-oriented argument is the is-a relationship. That is to say Class2 is a Class1. In C + + we say that Class2 is a derived class of Class1, or that Class1 is the base class for Class2. Aggregation and Composition Start with a relationship that is easy to understand. There is often a case where a class is a data member of another class.

Again, please note that the example provided below is based on the new UML 2 specification.
