ERD Diagram / Prototype Assignment (Fund Of Data Systems)

ERD Diagram / Prototype Assignment (Fund Of Data Systems)

ERD Diagram and Prototype Database

The goal of the project is to implement a “prototype” database system application and ERD diagram for an eCommerce social-network system called UCOnline where users can explore information about books/music/software, rate your purchase, identify purchase price and see ratings of their friends.

The project will require you to complete the assignment as a group. You will compete the assignment in the same groups you are to complete your Database Research Papers

Below you will find the ERD deliverable requirements. There are two parts to the assignment. You must create a diagram using a diagramming tool AND provide a written text-based document explaining your relationship mapping (systems analysis use case document). The assignment is worth 200 points. See rubric for grading scheme.
