## Overview

Danphe EMR is a web-based hospital management system spanning patient care, hospital operations, and finance. Its principal user workflow begins with patient registration and appointment or visit handling, continues through clinical documentation, orders and diagnostics, and can lead to admission, discharge, and billing. Accounting, inventory, pharmacy, reporting, and administrative capabilities form important operational branches. The README documents the breadth of modules; the sampled controllers show direct database-context usage, but do not establish all cross-module calls, so uncertain wiring is omitted.
