One of the most interesting and useful diagrams in the Unified Modeling Language is this Sequence Diagram for GUI (UML). It aids in the documentation and comprehension of dynamic aspects of your software system, specifically the Sequence of messages sent and received between objects. Sequence diagrams can assist you in understanding and resolving difficult issues in the process-intensive parts of your applications. Objects involved in the Sequence of events should be placed at the top of the sequence diagram across its horizontal axis. Then, on the diagram, you can place objects instantiated by the UI or other objects. The most important objects should be placed on the left, and the subordinate objects on the right.
