UML class diagram and uml class diagram
I. First of all, I declare that the learning of UML class diagrams refers to the example in "big talk Design Pattern" for personal learning and does not involve anything else.

Today we look at another element of the UML basic building block-the relationship.in UML, there are relationships that represent the basic diagram symbols, which are: Dependency (dependency), generalization (generalization, also known as inheritance), realNow (realization) and Association (Association), and the association is divided into common associations (common Association), Aggregation (aggregation,

"Purpose" indicates the different states in which a class is located and the process in which the class is converted in these states2. activity Map (diagrams)"Concept" describes the activities that are required to meet the use case requirements and the constraints of the active time"How to Describe"

My understanding of the relationship between uml class diagrams and my understanding of uml class diagrams
Relationship between uml class diagrams:
Generalization is inheritance. An Implementation relationship is a class that implements another interface. Dependency is a class that uses another class. It is a usage relationship. In a service of this class, anothe
If the elements in UML are basic words, the view is the syntax.
Sort out the views in UML:
Static View:
As the name implies, a static view is a view that expresses static things. It only describes the static structure of a thing and its dynamic behavior. Examples, class charts, and package charts are provided.

The UML (Unified Modeling Language) Chinese Unified Modeling Language is an open approach for explaining, visualizing, building, and writing an open approach to an object-oriented, software-dense system of artifacts. UML presents a series of best practices that are validated for modeling large-scale, complex systems, espec
: mapping, abstraction, merging, splitting, deduction, etc.The result of system analysis is to obtain the system of each analysis class, these analysis classes can basically be divided into entities, boundaries, control three categories, and the development of MVC exactly correspondingThe results of the analysis class are considered to implement the language and the implementation way, that is, the system design, the result is that the development can be directly used in the class, package and i
Recently, Sunny gave a two-day internal training on UML software modeling technology to a large Chinese enterprise over the weekend. The following is the outline of this internal training course:

actions, which are larger than the total number of elements. Therefore, collaboration is structured, actionized, and dimensional. A given class may be part of several collaborations. These collaborations represent the implementation of the system model. In UML, the collaboration is represented by an elliptic drawn by a dotted line and its name.

Last week a friend of mine, who is also a colleague of the company, recommended a UML tool for me to start using, but the more I used it, the more I felt good,

After summing up Ubuntu, we will continue to integrate UML. In the previous article, we introduced the Relationship Between the use case diagram and the use case. Let's talk about it now.Relationship between class diagrams and classes in UML.
When drawing a class chart, clarifying the relationship between classes is the focus. Class relationships i
13 types of uml and 13 types of uml
1. Use Case chart: Classification of the system usage.
2. Class diagram: displays the relationship between classes and them.
3. Object graph: displays only objects and their relationships.
4. Activity diagram: displays activities of a person or object in a way similar to a flowchart.
5. State Machine diagram: displays various states of objects with interesting or
the [object] name implies, all considerations of this technology start from object.
Object can improve the development efficiency and speed of large-scale software projects.
The so-called object pointing means to break down complicated problems in detail and express them in charts. For example
As shown in, a good model can correctly and reasonably express complicated meanings. After the complex path information is simplified, it becomes a clear and visible model diagram.
However, there are var
communicating with others and helping to solve design problems. The important point is that the level of detail in the diagram should be only necessary to achieve the goal. You can draw illustrations with lots of decorations, but that's a way to damage productivity. Make sure the diagram is simple and clean. UML diagrams are not source code and should not be used as a place to declare all methods, variable
First, let's talk about why we want to convert the format. The HTML format can be viewed through the web page, which is convenient for those who have not installed the software about UML.
I sent a picture to my master, and he said that he would change it to HTML format. How can this problem be solved? It's ration.If Rose comes with this function, it still needs to be converted through other software. Master said Rose can be directly transferred. Let's
, but it replaces the only class name in the top area. Its name is spliced:
Instance Name : Class Name
For example:
Donald : Person
Because the purpose of displaying instances is to display noteworthy or related information, it is not necessary to include the entire object attribute and operation in your model. On the contrary, it is entirely appropriate to only display the attributes of interest and their values. 16.

If you want to build a dog nest, prepare wood, nails, and some basic tools (such as hammers, saws, and tape ), you can start working. From developing a preliminary plan to completing a dog's nest that meets the appropriate functions, it may be possible to implement it within a few hours without the help of others. As long as the dog's nest is big enough and not leaking, the dog can live. If the desired effect is not met, rework is always acceptable, but it is nothing more than a grievance to the
