adduser () method can be defined as public Boolean adduser (userdto user). In the iuserdao method, adduser () the object of the userdto type is used as a parameter, so there is a dependency between iuserdao and userdto.

Class diagrams are also the most commonly used UML diagrams, with class diagrams showing classes, interfaces, and the static structure and relationships between them.2. Elements of a class diagramThe following model elements

The relationship between classes plays an important role in understanding object-oriented objects. I was often asked this question during interviews. Here I will introduce it.There is a relationship between the class a

A use case diagram is primarily a graph that represents the main event flow of a system. It is mainly used to describe the needs of customers, that is, users want the system to complete a certain function of the ability to understand the use case is the SOFTWARE function module. The designer creates and interprets a use case diagram based on the customer's needs
directly with each other, then these two classes should not have direct interaction, and if one of the classes needs to invoke a method of another class, the call can be forwarded through a third party.
The fundamental idea of this principle is to emphasize the loose coupling between classes, and the weaker the coupling between classes, the more beneficial the reuse, the more weakly coupled class is modified and does not affect the related classes. In the structure design of a class, each c

The recipient and sender of an asynchronous message are working concurrently. The return message means that the message is returned from the procedure call.Self-correlating messagesRepresents the method's own invocation and one method within an object that invokes another method, such as:Combined fragmentsRepresents a message sent wi

The object graph shows the static images of the instances, which are derived from the components established in the class diagram. The object graph deals with the static Design view or static process view of the system as if it were a class diagram. The difference is that it handles the view of a real or typical case.ACompo

Dependency: for example, logwapper depends on log,
The so-called dependency, the dependency program is relatively speaking, not necessarily because logwapper cannot "survive" without a log ".
In the specific business logic, logwapper needs logs to assist with the completion of a specific task, which is also dependent.

In UML, the implementation of use cases is specified and described using an interactive diagram. The interaction diagram shows the relationship between objects and the messages processed between objects to model the dynamic characteristics of the system.
