## Overview

Danphe EMR is a web-based hospital information and electronic medical-record system. Its broad user workflow spans patient and visit management, clinical care, diagnostics, admission and discharge, medication and inventory operations, billing, and accounting. The sampled ASP.NET controllers are the clearest runtime entry layer, coordinating domain operations with database contexts; the README documents additional product areas. The excerpts are partial, so the graph shows only supported controller-to-context links and avoids implying an end-to-end sequence between separate modules.

Main entry points: [`Code/Websites/DanpheEMR/Controllers/Radiology/RadiologyController.cs`](https://github.com/hospital-management-system-emr/hospital-management-system-emr-opensource/blob/master/Code/Websites/DanpheEMR/Controllers/Radiology/RadiologyController.cs) (Radiology imaging), [`Code/Websites/DanpheEMR/Controllers/Admission/AdmissionController.cs`](https://github.com/hospital-management-system-emr/hospital-management-system-emr-opensource/blob/master/Code/Websites/DanpheEMR/Controllers/Admission/AdmissionController.cs) (Admission and discharge), [`Code/Websites/DanpheEMR/Controllers/Emergency/EmergencyController.cs`](https://github.com/hospital-management-system-emr/hospital-management-system-emr-opensource/blob/master/Code/Websites/DanpheEMR/Controllers/Emergency/EmergencyController.cs) (Emergency care), [`Code/Websites/DanpheEMR/Controllers/Lab/LabController.cs`](https://github.com/hospital-management-system-emr/hospital-management-system-emr-opensource/blob/master/Code/Websites/DanpheEMR/Controllers/Lab/LabController.cs) (Laboratory)
