Database Project 1: Bookstore Management System
Introduction
The objective of this project is to design and implement a complete bookstore management system using a relational database. The system will allow users to manage books and customers effectively, enabling functionalities such as inserting, querying, and deleting records. For the development, we will leverage the Flask framework to create a web interface that connects to an AWS RDS instance running the database. This document outlines the design of the database, the functions implemented in the web application, and the project implementation details.
Database Design
Based on the provided E-R diagram, the database “Bookstore” will consist of the following tables:
1. Books
- BookID (Primary Key)
- Title
- Author
- Genre
- Price
- StockQuantity
2. Customers
- CustomerID (Primary Key)
- Name
- PhoneNumber
- Address
3. Orders
- OrderID (Primary Key)
- CustomerID (Foreign Key)
- OrderDate
- TotalAmount
4. OrderDetails
- OrderDetailID (Primary Key)
- OrderID (Foreign Key)
- BookID (Foreign Key)
- Quantity
- Price
The relationships between the tables depicted in the E-R diagram illustrate that:
- Each customer can possess multiple orders, while each order belongs to one specific customer (one-to-many relationship between Customers and Orders).
- Each order can contain multiple books, and each book can be part of multiple orders (many-to-many relationship between Orders and Books), which we resolve using the OrderDetails table.
To create the database and its tables, SQL scripts are used to ensure integrity constraints and relationships are maintained.
Functionality of the Web Application
The web application allows users to interact with the database using the following functionalities:
1. Insert Records:
- The application provides forms to input data for each table. For instance, when a new order is created, it automatically adjusts the stock quantity for the corresponding books, ensuring that inventory levels are accurate.
- Example code for inserting a new book:
```python
@app.route('/add_book', methods=['POST'])
def add_book():
title = request.form['title']
author = request.form['author']
genre = request.form['genre']
price = request.form['price']
stock_quantity = request.form['stock_quantity']
query = "INSERT INTO Books (Title, Author, Genre, Price, StockQuantity) VALUES (%s, %s, %s, %s, %s)"
cursor.execute(query, (title, author, genre, price, stock_quantity))
connection.commit()
return redirect('/books')
```
2. Query Records:
- Users can query books and customers based on various criteria, such as author, genre, or customer name. This is implemented using GET requests to retrieve and display data dynamically.
- Example code for querying books:
```python
@app.route('/books', methods=['GET'])
def view_books():
cursor.execute("SELECT * FROM Books")
books = cursor.fetchall()
return render_template('books_list.html', books=books)
```
3. Delete Records:
- The application allows users to delete entries from each table. Upon deletion, it checks for dependencies and updates related records where necessary.
- Example code for deleting a book:
```python
@app.route('/delete_book/
def delete_book(book_id):
cursor.execute("DELETE FROM Books WHERE BookID = %s", (book_id,))
connection.commit()
return redirect('/books')
```
Implementation Environment
For the development of the project:
- Backend Framework: Flask was chosen for its minimalistic design and ease of use in creating web applications.
- Database Management: AWS RDS was utilized to host the MySQL database, providing reliability and easy scalability.
- Front-end Technology: HTML, CSS, and JavaScript were used to build a user-friendly interface.
To run the application, users need to set up their local environment with Flask and MySQL libraries. For detailed setup instructions, a README file is included in the project folder.
Conclusion
The completion of this project has provided comprehensive knowledge in database design and implementation, as well as in developing web applications. By following the functionalities of inserting, querying, and deleting records, I have reinforced my understanding of relational databases and how they fit into a web application environment.

This project demonstrates the feasibility and efficacy of a database-driven web application in managing a bookstore, and addresses all requirements outlined in the assignment prompt. The combination of theoretical knowledge and practical implementation prepares students for real-world database applications.
