The Entity relationship diagram for a blood bank management system outlines critical entities like donors, recipients, blood requests, and appointments. The Donor entity tracks donor profiles, blood types, and last donation dates, while the Recipient entity manages patient details and transfusion needs. Blood requests are logged with statuses and volumes, ensuring timely fulfillment. Appointments link donors to staff-managed sessions, with Blood Bank entities storing location and contact data. This structured approach ensures efficient blood inventory tracking, donor-recipient matching, and emergency response coordination. Ideal for healthcare providers. The ER diagram highlights lifesaving workflows and regulatory compliance in blood donation systems.
