Book Management Database

Designing a book management database requires careful consideration of the types of data we need to store and how users will interact with it. Let's design a basic schema for such a database. This design will handle books, authors, categories, publishers, and user reviews.

  1. Tables & Their Attributes:

    • Authors:

      • AuthorID (Primary Key)
      • FirstName
      • LastName
      • BirthDate
      • Biography
    • Categories:

      • CategoryID (Primary Key)
      • CategoryName
    • Publishers:

      • PublisherID (Primary Key)
      • PublisherName
      • Address
      • ContactNumber
    • Books:

      • BookID (Primary Key)
      • Title
      • ISBN
      • PublicationDate
      • Summary
      • Price
      • AuthorID (Foreign Key to Authors)
      • PublisherID (Foreign Key to Publishers)
    • BookCategories (To manage many-to-many relationship between Books and Categories):

      • BookID (Foreign Key to Books)
      • CategoryID (Foreign Key to Categories)
    • Reviews:

      • ReviewID (Primary Key)
      • UserID
      • BookID (Foreign Key to Books)
      • Rating
      • Comment
      • ReviewDate
    • Users (For the sake of reviews):

      • UserID (Primary Key)
      • FirstName
      • LastName
      • Email
      • Password (hashed and salted)
  2. Relationships:

    • A book can be written by one author but an author can write many books. This is a one-to-many relationship between Authors and Books.

    • A book can have many categories and a category can have many books. This is a many-to-many relationship. Hence, we've introduced the BookCategories table to manage this.

    • A book can be published by one publisher but a publisher can publish many books. This is a one-to-many relationship between Publishers and Books.

    • A user can write many reviews, but each review pertains to a single book. This is a one-to-many relationship between Users and Reviews.

  3. SQL Creation Snippets (using generic SQL):

    CREATE TABLE Authors (
      AuthorID INT PRIMARY KEY,
      FirstName VARCHAR(100),
      LastName VARCHAR(100),
      BirthDate DATE,
      Biography TEXT
    );
    
    CREATE TABLE Categories (
      CategoryID INT PRIMARY KEY,
      CategoryName VARCHAR(100)
    );
    
    CREATE TABLE Publishers (
      PublisherID INT PRIMARY KEY,
      PublisherName VARCHAR(100),
      Address TEXT,
      ContactNumber VARCHAR(20)
    );
    
    CREATE TABLE Books (
      BookID INT PRIMARY KEY,
      Title VARCHAR(255),
      ISBN VARCHAR(13),
      PublicationDate DATE,
      Summary TEXT,
      Price DECIMAL(10,2),
      AuthorID INT,
      PublisherID INT,
      FOREIGN KEY (AuthorID) REFERENCES Authors(AuthorID),
      FOREIGN KEY (PublisherID) REFERENCES Publishers(PublisherID)
    );
    
    CREATE TABLE BookCategories (
      BookID INT,
      CategoryID INT,
      FOREIGN KEY (BookID) REFERENCES Books(BookID),
      FOREIGN KEY (CategoryID) REFERENCES Categories(CategoryID),
      PRIMARY KEY (BookID, CategoryID)
    );
    
    CREATE TABLE Users (
      UserID INT PRIMARY KEY,
      FirstName VARCHAR(100),
      LastName VARCHAR(100),
      Email VARCHAR(150),
      Password VARCHAR(255) -- hashed and salted
    );
    
    CREATE TABLE Reviews (
      ReviewID INT PRIMARY KEY,
      UserID INT,
      BookID INT,
      Rating INT,
      Comment TEXT,
      ReviewDate DATE,
      FOREIGN KEY (UserID) REFERENCES Users(UserID),
      FOREIGN KEY (BookID) REFERENCES Books(BookID)
    );
    

This is a basic design. In real-world applications, you would need to handle more advanced features like multiple authors for a book, book editions, stock levels, transactions, or even eBook file management. Adjustments can be made based on specific requirements.
