What do Data Flow Diagrams (DFDs) represent in systems analysis and design?

• The flow of data within a system or process

• The structure of a database and the relationships between entities

• The life cycle or history of entities within a system

• The steps and logic of a process or system

Which standardized symbols are used in flowcharts to represent different elements of a process?

• Rectangles for processes, diamonds for decisions, and arrows for flow direction

• Circles for processes, squares for decisions, and lines for flow direction

• Triangles for processes, circles for decisions, and arrows for flow direction

• Rectangles for processes, squares for decisions, and lines for flow direction

What do Entity-Relationship Diagrams (ERDs) represent in database design and systems analysis?

• The flow of data within a system or process

• The structure of a database and the relationships between entities

• The life cycle or history of entities within a system

• The steps and logic of a process or system

What are entities in ERDs?

• Objects, concepts, or data categories
