The purpose of this assignment is to analyze data in order to create a Level 0 DFD (data flow diagram) and an ERD (entity relationship diagram).
Refer back to the health club scenario from Chapter 4 Exercise G in the textbook. For this assignment, you have been tasked with creating a database system for the health club. Consider the type of data you will include for customer memberships, employee information, class schedules, trainer schedules, a juice and supplement bar, and equipment.
Create a level 0 DFD (data flow diagram) for the health club system. Summarize the DFD and justify your choices in a 250-500 word rationale that you submit with the DFD. A variety of programs such as Excel, Visio, Word, or PowerPoint can be used to construct the diagram, which should be saved as a PDF for submission to the instructor.
Create an ERD (entity relationship diagram) based upon the data you believe you will need for each of these categories. Summarize the ERD and justify your choices in a 250-500 word rationale that you submit with the ERD. A variety of programs such as Excel, Visio, Word, or PowerPoint can be used to construct the diagram, which should be saved as a PDF for submission to the instructor.
Submit the DFD, ERD, and the written rationales for each.
