hollow diamond. The diamond points to the whole.
5. Composition)
[Composite relationship]: it is the relationship between the whole and the part, but the part cannot exist independently from the whole. If the relationship between a company and a department is a whole and a part, no department exists without the company.
A composite relationship is a type of association relationship, which is stronger than an aggregation relationship. It requires that the object representing the whole in a gene
Today I saw a gossip news, Zhou Xun issued a statement and formally broke up with Li Daqi (http://ent.163.com/09/0624/15/5CJ6JK3F00031H2L.html) The so-called "no follow-up or no news" Netease comments, as always, also built a building, showing the infinite wisdom of netizens, there is a comment building is quite high, as shown below:
The characters in these periods are complex and difficult to clarify their clues. After reading it for a long time, I suddenly remembered that the
relationship between the whole and the part, and the part can exist independently from the whole. If a car and a tire are in the overall and partial relationship, the tire can still exist when it leaves the car. An aggregation relationship is a strong association relationship. The association and aggregation cannot be distinguished in syntax, and the specific logical relationship must be investigated. [Code embodiment]: member variables [Arrow and direction]: solid line with hollow diamond.

Combination.Relationship: The relationship between the whole and the part. But unlike aggregations, the parts here are inseparable from the arrangement. For example: The wings cannot be alone and must depend on the bird. Of course, in this logic, you say braised chicken wings, that relationship is not the same.Implementation: With solid diamond solid line, D
1. Introduction
In UML class diagrams, the following relationships are common: generalization (generalization), implementation (realization), Association (association), Aggregation (Aggregation), combination (composition), dependency ( Dependency).
2. Relationship
2.1 generalization (generalization)
Generalization relationships: An inheritance relationship that represents a general and special relationship
