A sequence diagram is a dynamic modeling tool that can be used to visually depict the logical order and flow of interactions between doctors and patients when accessing medical records, prescribing medications, or providing other related healthcare services. The diagram consists of steps in the process, including doctor-patient communication, accessing patient reports, performing diagnoses, checking for drug interactions, and writing prescriptions. This sequence diagram can help both doctors and patients better understand their roles in the appointment process and ensure they are both taking the necessary steps to successfully treat illnesses or injuries. With EdrawMax, one can easily create similar diagrams. EdrawMax also allows exporting such detailed diagrams in multiple formats, including Graphics and Office.
