Design and implement a SQL database for a library management system. The system should be able to perform the following operations:

1. Add Book: Insert a new book record into the database with details such as title, author, ISBN, and publication year.
2. Remove Book: Delete a book record from the database using the book’s ISBN.
3. Search Books: Retrieve and display books based on a search query that can include title, author, or publication year.
4. Check Out Book: Update the database to reflect that a book has been checked out by a member, including the member’s ID and the due date for return.
5. Return Book: Update the database to reflect that a book has been returned and is available for checkout again.

Requirements:

• Use SQL for database operations.
• Ensure that the database schema includes tables for books, members, and checkouts with appropriate relationships.
• Implement error handling for cases such as attempting to remove a book that does not exist in the database.

Sample SQL Code Structure:

-- SQL statements to perform the required operations

-- Add Book
INSERT INTO books (title, author, isbn, publication_year) VALUES ('Sample Book', 'Author Name', '1234567890', 2021);

-- Remove Book
DELETE FROM books WHERE isbn = '1234567890';

-- Search Books
SELECT * FROM books WHERE title LIKE '%Sample%' OR author LIKE '%Name%' OR publication_year = 2021;

-- Check Out Book
UPDATE checkouts SET member_id = 1, due_date = '2024-05-15' WHERE book_isbn = '1234567890';

-- Return Book
UPDATE checkouts SET member_id = NULL, due_date = NULL WHERE book_isbn = '1234567890';
