member variable;Dependency relationship (dependency)A dependency is represented by a set of dashed lines with arrows, such as a dependent on B; He describes the relationship of an object to another object while it is running;Unlike association relationships, it is a temporary relationship that usually occurs during operation and changes with the runtime, and dependencies can change;Obviously, the dependence also has the direction, the bidirectional dependence is one kind of very bad structure,

Class digraphs are graphs describing classes, interfaces, collaboration, and relationships between them. A class diagram is a part of a static view in the system. A static view can contain many class diagrams. Static views are used for Structural Modeling of the software system. They construct the vocabulary and rela

Class diagrams are the most commonly used diagrams in UML. We can see that class diagrams are very important. A class chart is a class digoal. The shape is very simple. It consists of a rectangle, two rectangles, or three rectangles. For example: The top column s

consistent.Just, the class involved in the association is logically a level, such as the student teacher above, but the aggregation involves the class is not a level.Look at the following example:It can be expressed as a has a/some B, at which point B is able to separate from a and exist independently. Without a car tire or a tire.Combination compositionThe composition relationship is a bit tighter than th

Overview The relationships in a UML class diagram include: Association, aggregation, composition, dependency, generalization, and Realization) Association(Association) Line representation, optional arrows, Is a relationship in a static structure, which tends to be a data relationship. The relationships in this static structure will be stored with the storage of

In Visio, the relationship between a package and a class is an inclusive relationship, and after the class is dragged into the folder of the package, the relationship is established, and the two-dollar correlation symbol can be set to: aggregation, composition.Interface: Hollow Circle + Straight line (Donald Duck class to achieve ' speaking ');Dependency: Dashed

When drawing a class diagram, it is important to clarify the relationship between classes and classes. The relationships of a class are generalized (generalization), implemented (realization), dependent (Dependency), and associative (association). The association is divided into general relationship and aggregation relation (Aggregation), synthesis relation (comp

1, Inheritance relations: Hollow triangle + solid line.2, realize the interface: Hollow triangle + dashed line.3. Aggregation relationship: Hollow Diamond + solid arrow. Aggregation represents a weak ' owning ' relationship, which shows that a object can contain a B object, but the B object is not part of a.4. Composition (combination) Relationship: Solid diamond + Solid line arrow. Synthesis represents a strong ' owning ', which embodies the strict part and the whole relationship, part and the
