generation.Note: In the final code, the dependency is represented as an incoming parameter to the class constructor method and the class method, and the arrow points to the call relationship. dependencies, in addition to temporarily knowing each other, "use" each other's methods and properties.Third, time series diagramIn order to show the interactive details between objects, time series diagrams are generally used when learning

-UML class diagrams are often used to describe the static structure between classes when describing the design mode. The purpose of this article is to allow the readers to understand the UML class diagrams and to figure out several relationships in the

The key to the processing of object-oriented problem is the modeling problem. Modeling can abstract many important details in a complex world. Many modeling tools encapsulate UML (that is, unified modeling language™), a course designed to showcase the highlights of UML. UML has nine modeling icons, namely: Use case diagram Class Diagram object graph order diagram

decoupling. Two-way arrows indicate interdependence. nested : Inside the package can have a package. However, you should try to avoid the use of multi-layer nested package, 2-3-storey. Package diagram example Take the bookstore online ordering system as an example Package Diagrams Precautions -If the package is revoked, then the elements will be removed -Reasonable minimizati

Class diagram is used to describe the classes contained in the system and the relationship between them, to help people simplify the understanding of the system, it is an important product of the system analysis and design phase, but also the system coding and testing important model basis. Let's talk about the composition of the class diagram, and we'll discuss the relationship between class diagrams in th

I. OverviewWebsites are often complex and highly dynamic. To enable Web applications to run in a short time, the development cycle should be as short as possible. In many cases, developers directly enter the code writing phase, but do not carefully consider what kind of website they want to construct and how they are prepared to construct: server-side code is often written in an unprepared form, database tables are also on demand, and the entire application system sometimes shows a non-planned s

In the first part, we implement five classes. This section describes how to use UML class diagrams to design the remaining classes. To reduce the length, this section focuses on UML class diagrams and applications, and does not describe the Java implementation code in detail

Source code to reverse engineer the generation of UML classes and sequence diagrams. Reverse engineering is often used to derive lost design documents from exist

SummaryThis article briefly analyzes and designs an example of a "Student Course Selection System" to illustrate the two functions and forms of a class diagram in a UML diagram, in order to clarify the misunderstandings and confusions that some friends may have on class diagrams. PrefaceWith the popularity of OOA and OOD, UML has been widely used in system anal

the relationship, the child use case and the parent use case similar, but shows a more specific behavior, the child use case will inherit all the structure, behavior and relationships of the parent use case. A child use case can use a section of the parent use case, or it can be overloaded. The parent use case is usually abstract. (PS: Arrow pointing--pointing to the parent case) contains: The containment relationship is used to break down the functionality represented by a more complex use cas
