The goal of this project is to create an SQL database for a travel company that offers travel packages to customers. The database includes tables for customers, travel packages, categories, and a link table between packages and categories. It also includes triggers for updating the sum of reserved packages in each category and a stored procedure to find the number of reserved packets and the total cost for a given customer email.

The program defines a database schema named travel_packets that stores information about travel packets, customers, and categories of travel packets. The schema includes several tables such as packets, customers, chosen_packet, and category. The packets table stores information about each travel packet such as its destination, start and end dates, transport, and cost. The customers table stores information about customers such as their name, address, phone number, and email. The chosen_packet table stores the chosen packets for each customer. The category table stores information about different categories of travel packets and the number of reserved packets for each category. The program also includes a function named duration() that calculates the duration (in days) of each package in the packets table. Additionally, there is a procedure named find_packets() that takes an input parameter client_email and returns the number of reserved packets and total cost for the customer with the specified email.i Finally, the program defines three triggers that update the sum_reserved field in the category table whenever a row is inserted, deleted, or updated in the chosen_packet table. This ensures that the number of reserved packets for each category is always up-to-date.
