A Send Signal in an Activity Diagram represents an action that transmits a signal or message to another part of the system or to an external entity. It's used to model asynchronous communication between different parts of a process or system.
With Send Signals in Modeldraw's Activity Diagram, you can:
Represent the transmission of information or triggers to other parts of the system
Model asynchronous communication in your processes
Show how one part of a system can initiate actions in another part
Illustrate event-driven behaviors in your workflows
Demonstrate interactions between different components or actors in your system
A Send Signal in Modeldraw's Activity Diagram tool is typically represented by a convex pentagon (a rectangle with a point on one side). Key points to understand about Send Signals include:
It represents sending a signal without waiting for a response.
The Send Signal doesn't wait for or expect an immediate reply.
It can initiate actions or processes in other parts of the system.
The signal being sent is usually named to indicate its purpose or content.
After sending a signal, the flow in the current activity typically continues.
Can be used to show communication across system or component boundaries.
Remember that Send Signals are often used in conjunction with Accept Signals in other parts of the diagram or in separate diagrams to show the complete communication.
