Since UML (Unified Modeling Language) is often used in development, especially in the OOAD stage of software development, it is particularly important to understand and use UML. Before starting with UML, let's review the main features of OOAD and OOP. OOAD: The process of a

that the implementation class points to the interface, the arrow is a triangle, and the line is a dotted line. 3. Link: A) one-way Association: As far as chasing mm is concerned, many people seldom find her, but she is not uncommon. B) two-way Association: for husband and wife, a man can only have one wife, while a woman can only have one husband. C) Self-Association: Typically, in the menu, the sub-menu and the parent menu encapsulate the same data, but the menu class must have its own refe

UML is generally used in case-driven, architecture-centric, iterative, and incremental development. UML uses the following five views to describe the architecture of the software system: User Model View-use case diagram to describe system functions from the outside Structure Model View-class charts and object graphs, describing classes, objects, relationsh

structured, emphasizing the organization of the system. It can also be behavioral, emphasizing the dynamic aspect of the system.Why modeling? One basic reason is:Modeling aims to better understand the system being developed.Through modeling, we need to achieve four goals:(1) The model helps to visualize the system based on the actual situation or the style required.(2) The model can regulate the structure

If you want to distinguish these things from the build modules defined in UML, you can create a new build module by using the model, it is used to describe these new semantics and provide a unique visualized mark. 3.
