Diagram 1. Processes Processes are activities or functions that manipulate data. They are typically represented by rounded rectangles or circles, indicating an action or transformation within the system. Each process should have a unique name describing its function, such as "Verify Payment"
evolving to accommodate these innovations. Modern SIMS increasingly handle real-time data streams, predictive analytics for student performance, and automated communication systems. In this context, DFDs must expand to represent new data sources, such as learning management system
