A System Architecture Diagram is a representation of the interactions among patients, physicians, and pharmacies within a digital healthcare system. This diagram visualizes the communication process between the patient and doctor, from logging into the application to receive over-the-counter medicines to the doctor downloading the required prescribing medications. The architecture also illustrates how orders for medications are placed at the pharmacy, how data about patients is stored or retrieved from a server, and finally, how the patient will receive their medication. You can download EdrawMax to create a similar system architecture diagram.
