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 ASSIGNMENTSYou will work with book/music/media information, user information, ratings of books, and users’ social networkEach book has an id, title, publication date, publisher, ISBN, functional category, page count, price (publisher), and product descriptionThere are 3 categories of book: fiction, non-fiction, and specialtyThere are 2 categories of music: digital and media-basedAn author can write one or more books.A musician can be a solo artist, part of a group, or bothAn author can also be associated with one or more publishers.A musician/group/act can be associated with one or more music housesAn author’s book can have one or more editions.A song and or album can have more than one version/edition (i.e. EP, LP, CD, DVD etc)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).Using the use case list above, you are to submit the following as your final project as a GROUP.(a) Working ERD Diagram(b) Explanation of the relationships used in the ERD Diagram (text-based summary)(c) URL of a WORKING database that maps your database solution. It should be a working prototype. I strongly encourage you testing this and using this as an opportunity. There are many free offers for AWS, Azure, GCP available - especially for students.Using the use case list above, you are to submit the following as your final project as a GROUP.(a) Working ERD Diagram(b) Explanation of the relationships used in the ERD Diagram (text-based summary)(c) URL of a WORKING database that maps your database solution.

This is an individual assignment due on Saturday (8 May) at 11:59 pm. As an open book project, you may reference notes and other course material, but you may not work together, or receive help from anyone except staff members. Otherwise, it is just like a normal lab assignment: you may use PythonTutor or other IDEs, and you may submit as many times as you'd like. We will not be style-checking this assignment.MOSS: A Word on Plagiarism DetectionPlease keep in mind that as computer science instructors, we care about academic dishonesty just as strongly as our peers in other fields of study. Unlike our peers, however, our field of expertise and the nature of the material allows us to create tools that enhance our detection of plagiarism. I'm sure you have heard of similar tools, such as TurnItIn.com, and other plagiarism detection systems for essays. Since our field is more mathematical, however, we are capable of considering not only the actual text written on the screen but the overall flow and intent of the program, and mathematically compare it to that of another to determine the level of similarity between the two. Therefore, I highly suggest that you do not "collaborate" with anyone else, as we will be able to detect it. If we catch you cheating, you will receive an automatic zero in the class, and your case will be sent to the Office of Academic Integrity & Student Conduct. With that being said, let's all take a deep breath and try to have some fun!PreambleAt this point in the course, you have enough knowledge about Python to do more than you think. Many simple games, for example, can be written with what we've already covered. So let's do it!
