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

boxed drinks with a unit price of 1.5 yuan. If you invest 1.5 yuan coins, press "Cola", "Sprite", or "black tea" button, the corresponding drink will be sent out. If you invest in a 2-dollar coin, return the 5-point coin at the same time you send the drink.Analysis:Reason: ① put 1.5 yuan coins, ② put 2 yuan coins; ③ Press "Cola" button; ④ Press "Sprite" button; ⑤ Press "black tea" button. Middle Status: ① has been cast, ② has been button. Results: ① returned 5 cents, ② sent "cola" drink ③ Sent

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

"and" the relationship between the combination of the same can be correctly mapped to the corresponding index. This is common for other Asian languages: Korean and Japanese.The biggest advantage of automatic segmentation is that there is no thesaurus maintenance cost, simple implementation, disadvantage is low index efficiency, but for small and medium-sized applications, based on the 2-yuan syntax segmentation is sufficient. Based on the 2 yuan after the segmentation of the index general size

Relationship between The following example will show the relationships independently for a specific purpose. Although the syntax is correct, these examples can be further refined to include more semantics within their valid range.Dependence (Dependency) A "use" relationship between entities implies a change in the specification of an entity and may affect other instances that depend on it ( figure D). More specifically, it can be converted to any type of reference to a
