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 (composition). Here we understand these relationships in conjunction with examples.Basic concep
