A bookstore plans to develop a Book Store Management System (BSMS) to streamline both in store and online operations. The system will allow customers to browse books, search by title, author, or category, view detailed information, add selected books to a shopping cart, place orders, make online payments, and track their order status from placement to delivery. Customers will also be able to submit reviews and feedback on purchased books. Store employees will use the system to manage daily tasks such as adding new books to the catalog, updating stock quantities, processing customer orders by confirming, packing, and shipping them, handling complaints, and managing returns or refunds. The system will maintain several key data stores, including customer profiles, book catalog details, supplier information, order histories, payment records, and inventory levels. The BSMS is expected to efficiently support workflows such as order processing, inventory restocking, supplier management, and return or refund operations, ensuring smooth interaction between customers, employees, and administrators.
