continue today to see the diagrams in the UML basic building blocks. a diagram of a UML basic building block A diagram of a UML basic building block is an abstract description of the system in a specific perspective. A graph is the classification of a collection of things, and UML contains many diagrams. Let's look at

Since the formal release of UML in 1997, a large number of commercial UML modeling CASE tools have appeared. This provides us with a lot of options and requires us to select the correct UML modeling tool to better adapt to our business and software application development needs, do a lot of research to achieve the best

Four types of relationships and code implementation of class diagrams in UML, and four types of uml In the uml diagram, the most complex relationships are generalization, implementation, dependency, and association, if you understand these relationships, you will become familiar with understanding the UML diagram! If y

and the operation personnel at all levels involved in the project, identify all use cases and roles in the system through analysis; next, analyze the relationship between roles and use cases in the system, use the UML modeling tool to draw a system use case diagram, and sketch the concept layer model of the system, use a UML modeling

In this section, we will look at another important principle: OCP principle (Open-Close principle ).Software entity shocould be open for extension, but closed for modificationReview in the previous section: 1.

concepts (such as abstraction, classes, and objects) and mechanisms in the problem domain need to be identified and their relationships need to be described using UML class diagrams.To implement use cases, classes need to collaborate, which can be described using the UML dynamic model. In the analysis phase, only the objects in the problem domain (concepts in the real world) are modeled, classes that defin

models in analyzing the conceptual integrity of software system models. Since the schema is well-described and documented, We can frequently use this knowledge for View analysis in terms of structure and behavior. As shown in the following figure, the schema knowledge can be used to map views (cross-reference of modeling information) or transform information from one view to another. Later, we explained the abstract and transformation technologies. Although the purpose of creating a view integr

Uml and other diagrams, Uml In object-oriented processing, class graphs are at the core and provide the main rules for defining and using objects. It is a diagram describing classes, interfaces, and their relationships. It shows the static structure of each class in the system and is a static model. I. Class Diagram 1. Class A class is the basis for creating a class chart. It defines a group of objects wit

　　When I mentioned UML before, I thought of the complicated flowchart. I admire the people who think about the UML diagram of the whole system, because they have the blueprint of the whole software architecture in their mind, so that when writing the implementation, they will know where to change and where to expand. And to be an architect, UML is also an ess

There are many types of UML diagrams, only two of the most important and common-class and time series diagrams are discussed here. 1. Class Diagram through the class diagram, we can easily understand the code architecture, clarify the relationship between the modules, includes inheritance (inheritance), implementation (realization), dependency (dependency), composition (composition), Aggregation (Aggregation), Association (association), and so on.

Classes may have the following relationships: Association, dependency, aggregation, aggregation, composition, and generalization, also known as inheritance), implementation (realization ). 1: Association refers to the relationship between two classes. For example, a customer and an order can only belong to one customer. A customer may have multiple orders. It can be divided into one-way and two-way directions. It can be divided into one-to-one, one-to-multiple, and many-to-many based on the corr

It is simple, happy, and efficient for you to let him cook a table of food. However, programming will become an annoyance and hard nut to crack. Maybe this metaphor is not very appropriate, but for every class, they are like an actor, ma

Three main elements of modeling: 1. Basic Construction blocks of UML; 2. Rules on how to put these constructor blocks together; 3. Some common mechanisms applied to the entire UML; The UML constructor consists of three types: A, thing B, relationship C, and diagram.
