Extracted text: CASE STUDY 1 Draw an appropriate Context Diagram for the following case study. State any assumption for the diagram. When a patient arrives at Malaysia-Mesra Surgery with a repeat prescription request, the receptionist checks the prescription file and writes out a prescription. This has to be authorized by the doctor before being passed to the resident chemist for dispensing. The chemist then gives the prescription to the patient. If the patient is entitled to free prescriptions, the chemist verifies this and fills in the appropriate details on a form, which is filed in the free prescriptions file. Otherwise, the chemist takes the appropriate amount of money from the patient and gives them a receipt.
