+### Association bidirectionnel

+direction LR
+A -- B
+```
+
+```plantuml

+
+### Association unidirectionnel
+```plantuml
+@startuml
+class A
+A -> B : "                                                  "

+```
+
+### Aggregation bidirectionnel
+```plantuml
+@startuml
+class A {
+-ptrB: B*
+}
+class B {
++ptrA: A*
+}
+A "+ptrA" o- "-ptrB" B : "                                                  "

+
+### Composition (pas bidirectionnel)
+```plantuml
+@startuml
+class A {
+#aB: B
+}
+A *-> B : "                                                  "
+@enduml
+```
+
+### Dépendance
+```plantuml
+@startuml
+
+A .> B : <<usage>>\n<<include>>\n<<import>>\n"                                                  "

+
+### Généralisation
+```plantuml
+@startuml
+class "A extends B" as A
+class B {
+-myFunc(a: integer): void
+}
+A <|- B : "                                                  "
+@enduml
+```
+
+### Implémentation
+```plantuml
+@startuml
+interface B
+A .|> B : "                                                  "
+@enduml
+```
+
+## Timing
