1. IntroductionIt has been two years since I began to learn programming from a freshman year. From the initial study of the Html,js,javese, to Javaee,android, I can also write some toys. The learning process also unconsciously understood some of the so-called design Patterns , and now intends to learn the system. Learn to book the art of Design mode----------------------the software developer. The so-called design patterns, that is, the predecessors of a similar problem of the abstract solution

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, you must perform the following steps repeatedly to modify the sixth chapter of the object entry level 2. Step 1: define the range of the activity

(Dependency) definition: for two relatively independent objects, when one object is responsible for constructing an instance of another object, or depending on the service of another object, the two objects are primarily dependencies. performance: dependencies are expressed in local variables , the parameters of methods , and calls to static methods . Example: If you're going to screw the screws, do you want to use (ie rely on) a screwdriver (screwdriver)

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. Through the above analysis, the instance reference Class 1 is shown in Figure 1: Figure 1 Reference class diagram of the registration function Note:When drawing a class diagram or other

In UML class diagrams, the following relationships are common: Generalization (generalization) Implementation (Realization) Association (Association) Aggregation (Aggregation) Combination (composition) Dependency (Dependency) The order of strength of the various relationships:Generalization = implementation > Composition > Aggregation > Association > dependenciesFirst, generalization (generalization):The inheritance r

Case modeling is a part of UML modeling and the most basic part of UML. The main function of case modeling is to express the functional requirements or behaviors of the system. To put it bluntly, it is to explain what the system is, so you don't have to worry about how to work. I think the use case chart is the best picture in the analysis phase, because the content is very macro. Understand the elemen

Activity diagram, her English name is active Diagram, a workflow that describes the implementation of a business use case, which is one of the none of the diagrams used in the UML family to model dynamic aspects of the system. To give a simple example, to build a work flow for example, first of all, we have to select an address, and then commissioned an architec

The activity diagram is another common tool used by UML to model the dynamic behavior of the system. It describes the activity sequence and shows the control flow from one activity to another. An activity chart is essentially a flow chart. The activity diagram focuses on the control flow from one activity to another. It is an internal processing-driven process. T

Object Class diagram: Class, attribute, connection (Association, generalization, aggregation, combination, dependency), interface, and constraint. (Note: static attributes are underlined) Interface ). The operation set used to describe a service of a class or component. Data Type (datatype ). A type whose values are unchangeable, including simple built-in types (such as numbers and strings) and enumeration types (such as Boolean ). Associ

I haven't studied UML for many days because of the exam, and I feel a little unfamiliar. So hurry up and make up for my inner emptiness. We have to take the test this afternoon, and there is still nearly two hours in the middle. Now I will share with you my understanding of the object diagrams in UML. Of course, I have concluded that I have never drawn any picture, in the future, we will add the picture in

composite relationships. Generalization ): 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. Class "recursion" relationship and "Triangle" Relationship Recursive relationships are self-contained relatio

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

PrefaceI have been using php for more than two years. I have prepared to write frequently-used design patterns based on my own practical experience. Of course, before using the design patterns, I must first understand the design patterns, therefore, we will first explain the UML class diagram. Through UML class diagrams, we can better communicate with you and exp
