Glocare Pharmacy Management ER diagram models a relational database for retail pharmacy operations with five core entities. Supplier feeds Drug inventory via foreign key relationship, while Patient connects to both Appointment scheduling and Sale transaction records. The schema captures supplier contact details, drug attributes including expiry tracking and stock levels, patient demographics, appointment scheduling, and point-of-sale transactions linking patients and drugs. This normalized design supports inventory management, patient history, appointment workflows, and sales reporting for pharmacy staff and administrators.
