The goal of the project is to implement a “prototype” database system application / 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 individually. 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).
