Sequence Diagram Uml. That does not change the drawing but may improve readability. Unified modelling language uml is a modeling language in the field of software engineering which aims to set standard ways to visualize the design of a system.
Sequence diagram describes an interaction by focusing on the sequence of messages that are exchanged along with their corresponding occurrence specifications on the lifelines. On the top you can see the beginning and then the diagram flow descends downwards to mark the sequence of all interactions in the system. Uml guides the creation of multiple types of diagrams such as interaction structure and behaviour diagrams.
Uml sequence diagram is a type of interaction diagrams that describes the interactions between objects and classes that are involved in the scenario and the sequence of messages exchanged between them.
They capture the interaction between objects in the context of a collaboration.
