Microsoft Visio Level 1 Data Flow Diagram – Gym System

Hello, I need assistance with a Microsoft Visio assignment involving a Level 1 Data Flow Diagram (DFD) for Avery's Gym System.

The assignment requires Gane and Sarson notation, not UML notation.

The diagram must cover three major processes:

1. Collect Gym Member Information
2. Schedule or Change Fitness Assessments
3. Communicate Appointment Reminders

It must also include the appropriate external entities, the Gym Member Database, the Assessment Calendar, and correctly labeled data flows.

The instructions contain incomplete information, so reasonable assumptions are necessary to connect everything logically.

Important requirements:

• Use Microsoft Visio and Gane and Sarson symbols.
• Ensure all data flows pass through processes where required.
• Correctly connect external entities, processes, and data stores.
• Include the reminder postcard sent one week before appointments and text reminders sent one day before.
• Provide the original editable Microsoft Visio (.vsdx) file.
• Make sure the diagram is readable, organized, and follows all assignment criteria.

Please confirm that you have experience creating Level 1 DFDs using Gane and Sarson notation in Microsoft Visio.

Thank you.
