## Overview

This repository describes a postgraduate admissions-management system, with related requirements and design materials for a broader training-system context. The documented high-level workflow is users working through web or mobile interfaces with backend APIs and core business logic; a SQL schema is also present. Source excerpts were unavailable, so the graph stays at documented subsystem level and does not infer detailed admissions stages or internal call sequences.

Main entry points: [`Backend`](https://github.com/dh24pm-cnpm-nhom09/dh24pm-cnpm-nhom09/tree/main/Backend) (Backend API), [`Frontend`](https://github.com/dh24pm-cnpm-nhom09/dh24pm-cnpm-nhom09/tree/main/Frontend) (Web frontend), [`admission_db_v3.sql`](https://github.com/dh24pm-cnpm-nhom09/dh24pm-cnpm-nhom09/blob/main/admission_db_v3.sql) (Admissions database)
