Learning Goal: I’m working on a databases project and need an explanation and answer to help me learn.
Develop an Entity Relationship Diagram based on the Data Stores represented in the Data Flow Diagram created in Assignment-1.
You can include any additional Data Stores needed to complete the ERD.
You can add a Primary Key to each Table (Usually an Integer).
In Access Database you can specify this as “Auto Increment”. (You don’t have to use Access!).
All relationships in the ERD must be complete and consistent with the Data Stores shown in DFD.
Upload your ERD as a MS Word Document.
