Sequence Diagram
The sequence diagram
The key to dealing with object-oriented problems is modeling. Modeling can abstract many important details in the complex world. Many Modeling tools encapsulate UML (that is, uniied Modeling Language ).
There are nine types of modeling icons in UML:

In UML, the implementation of use cases is specified and described using an interactive diagram. The interaction diagram shows the relationship between objects and the messages processed between objects to model the dynamic characteristics of the system.
