What notations do you mainly work with?

The most commonly used notations by a systems analyst are:

• UML (Unified Modeling Language) — for modeling processes, classes, sequences, and interactions.
• BPMN (Business Process Model and Notation) — for describing business processes and workflows.
• ER diagrams (Entity-Relationship) — for designing and visualizing data structures.

These notations help structure requirements, visualize architecture and processes, and facilitate communication with the team and clients.
