Database Schema:import sqlite3
# Create a connection to the database
conn = sqlite3.connect('bookstore.db')
cursor = conn.cursor()
# Create the Authors table
cursor.execute('''CREATE TABLE Authors (
author_id INTEGER PRIMARY KEY,
author_name TEXT
)''')
# Create the Books table
cursor.execute('''CREATE TABLE Books (
book_id INTEGER PRIMARY KEY,
book_title TEXT,
publisher_id INTEGER,
price REAL,
FOREIGN KEY (publisher_id) REFERENCES Publishers(publisher_id)
)''')
# Create the Publishers table
cursor.execute('''CREATE TABLE Publishers (
publisher_id INTEGER PRIMARY KEY,
publisher_name TEXT
)''')
# Create the Customers table
cursor.execute('''CREATE TABLE Customers (
customer_id INTEGER PRIMARY KEY,
customer_name TEXT
)''')
# Create the Book_Authors table
cursor.execute('''CREATE TABLE Book_Authors (
book_id INTEGER,
author_id INTEGER,
FOREIGN KEY (book_id) REFERENCES Books(book_id),
FOREIGN KEY (author_id) REFERENCES Authors(author_id)
)''')
# Create the Book_Customers table

book_id INTEGER,
customer_id INTEGER,
purchase_date DATE,
FOREIGN KEY (book_id) REFERENCES Books(book_id),

cursor.execute("INSERT INTO Publishers (publisher_name) VALUES ('Publisher 1')")
cursor.execute("INSERT INTO Publishers (publisher_name) VALUES ('Publisher 2')")
cursor.execute("INSERT INTO Books (book_title, publisher_id, price) VALUES ('Book 1', 1, 19.99)")
cursor.execute("INSERT INTO Books (book_title, publisher_id, price) VALUES ('Book 2', 2, 24.99)")
cursor.execute("INSERT INTO Customers (customer_name) VALUES ('Customer 1')")
