You are making my life so much easier! I am a single mom that works and goes to school. You guys are helping me with my projects so I can have more free time with my son.
The goal of the projects throughout this semester is to implement a “prototype” database system application for a 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 your teams (see attached for group member breakout) to complete the assignment. Below you will find the ERD deliverable requirements. Each assignment has a specific grading rubric (scheme) associated with the assignment.
BUSINESS REQUIREMENTS ACROSS ALL ASSIGNMENTS
You will work with book/music/media information, user information, ratings of books, and users’ social network
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).
