Question

Create a diagram using a diagramming tool AND provide a writt Create a diagram using a diagramming tool AND provide a written text-based document explaining your relationship mapping (systems analysis use case document). Requirements: You will work with book/music/media information, user information, ratings of books, and users’ social network. Each book has an id, title, publication date, publisher, ISBN, functional category, page count, price (publisher), and product description. There are 3 categories of book: fiction, non-fiction, and specialty. There are 2 categories of music: digital and media-based. An author can write one or more books. A musician can be a solo artist, part of a group, or both. An author can also be associated with one or more publishers. A musician/group/act can be associated with one or more record labels (consider this a possible type of publisher). An 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 - i.e., think Amazon). Many ISBNs can also be associated with a given publisher but only one ISBN per form of medium (i.e., 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 item 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.

The purpose of this paper is to explore the intricate relationships among various entities involved in a book, music, and media catalog, focusing on user interactions and rating systems. This analysis aims to elucidate the components such as books, music, authors, users, ratings, publishers, and record labels, and how they interconnect to maintain a comprehensive online store for UCOnline. Understanding the Entities In our system, the primary entities are Books, Authors, Musicians, and Users. Each of these entities possesses distinct attributes and relationships with one another. For instance, a book is characterized by its unique ID, title, publication date, ISBN, functional category, page count, price, and product description. The classifications for books are fiction, non-fiction, and specialty. Music can be categorized into digital and media-based, with musicians being identified as solo artists, part of a group, or both. Relationships among Entities Understanding the relationships between entities is crucial. An author can write multiple books, establishing a one-to-many relationship. Similarly, a musician can produce several songs or albums and may be associated with multiple record labels. A publisher holds the capability to publish many books and manage numerous authors, thus forming a many-to-many relationship between authors and publishers. A diagrammatic representation of these relationships is vital for visual learners and aids in comprehending the overall architecture of the system. The diagram outlines how each entity relates to one another. For example, a publisher can oversee many authors, and in turn, many authors can contribute multiple books through various editions. Users and Ratings The user rating system is pivotal as it allows users to express their opinions on various items within the online store. Each user is identified by a unique ID, with accompanying attributes such as name, gender, age, and location. Users can rate each book or media it
