Creating a Blood Bank Management System involves several components, including a MySQL database schema, file structure, layout design using Bootstrap 5, and complete PHP scripts for user authentication and management. Below is a comprehensive guide to help you set up your system.

Project Introduction

The Blood Bank Management System is a comprehensive web application designed to streamline the processes involved in blood donation, inventory management, and distribution. This platform serves as a bridge between donors, hospitals, and blood bank staff, ensuring efficient management of blood resources. It provides functionalities for user management, event organization, blood donation tracking, and compliance monitoring, all aimed at enhancing the overall efficiency of blood donation operations.

Project Objectives

• To create a secure and user-friendly platform for managing blood donors, donations, and inventory.
• To implement a robust database schema that supports various functionalities such as user roles, donation events, and blood testing.
• To facilitate real-time tracking of blood inventory and distribution to hospitals.
• To ensure compliance with health regulations through a dedicated compliance management module.
• To provide a feedback mechanism for donors to improve service quality and donor experience.
• To develop a notification system to keep users informed about important updates and events.

Project Modules

1. User Management: Manages user registration, authentication, and role assignments (admin, staff, donor, hospital).
2. Donor Management: Handles donor information, eligibility status, and donation history.
3. Donation Events: Organizes and manages blood donation events, including event details and scheduling.
4. Blood Donations: Tracks individual blood donations linked to donors and events, including blood type and donation date.
5. Blood Inventory Management: Monitors blood types, quantities, expiration dates, and storage conditions.
6. Blood Testing: Records testing results for blood donations to ensure compliance with health standards.
7. Blood Distribution: Manages requests and distribution of blood to hospitals, including tracking delivery dates.
8. Notifications: Sends alerts and messages to users regarding important updates and events.
9. Feedback System: Collects donor feedback and ratings to enhance service quality.
10. Compliance Management: Ensures adherence to health regulations and standards through a dedicated compliance module.
