create$\_$tables: Executes SQL statements to create tables for products, customers, inventory, transactions, suppliers, and staff if they don't already exist.

add$\_$product: Prompts the user to enter details for a new product $($name$,$ price, variant$),$ then executes an SQL INSERT statement to add the product to the Product table.

update$\_$product: Prompts the user to enter the ID of the product they want to update, as well as the new name, price, and variant. It then executes an SQL UPDATE statement to modify the product in the Product table.

remove$\_$product: Prompts the user to enter the ID of the product they want to remove, then executes an SQL DELETE statement to remove the product from the Product table.

execute$\_$transaction: Demonstrates a transaction by executing multiple SQL statements within a transaction block. In this example, it adds an invoice to the Transaction table and updates the inventory.

retrieve$\_$products: Executes an SQL SELECT statement to retrieve all products from the Product table and print their details.
