Diagram Description (Systems Analysis Text) in PDF Format

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). The assignment is worth 30 points. See rubric for grading scheme.

A publisher can have many authors and many books.
A record company can have many artists associated and many albums associated with it.
A record company can also be the publishing company (i.e. self-publishing)
Many ISBNs can also be associated with a given publisher but only one ISBN per form of medium (ie the ISBN is the PK no matter what).
An author can write many books.
An artist can write many songs, albums etc.

UCOnline needs to keep track of user ratings for each item sold in the online store (e.g., 1-5 and 1 for Dislike, to 5, for Awesome!).

A particular user rates a particular item at a given time.

A user CANNOT rate the same multiple times unless there are multiple editions of the item. Each edition can be rated separately.

Each user who submits a rating will be identified by a unique id and has a name, gender, age, and location. Nothing is anonymous.

There is also a social network between users. Users can send communication requests (i.e. instant messages/emails) to other users. Such requests can be accepted or ignored. Once accepted, the two users are considered book buddies. If ignored, the user can send the request again. We want to add a store when the requests were sent (timestamp), the result of the requests and when the request was answered (timestamp).
