Case Study – Patient information System
Design the DFD for a Patient information system. This system can be used for keeping track on

the record and activities of patients in a hospital. At first, the patient will arrive at the reception

for registration. After the registration and payment the patient can get appointment with a doctor.

The doctor will see the invoice and diagnose the patient.
If investigation is required the patient will go to the lab and give sample. Once the investigation

is complete his report would be printed and given by the lab technician. The technician will also

send a copy of report to the concerned doctor. After getting the report the patient visits the doctor

again. The doctor prescribes medicine and sends the patient to the pharmacy.

There, the patient take medicine and make the payment. If no investigation required, the patient

is directly sent to the pharmacy, where he can take medicine on payment. The medicine

inventory is updated accordingly
