## Overview

#### Purpose and Runtime
This repository is a server-rendered Student Management System providing CRUD operations and search over MySQL-backed student records. It runs as a Python/Flask application, started through `app.py`, and serves HTML pages plus static CSS assets.

Core paths: `app.py`, `requirements.txt`, `templates/`

#### Application Entry and Routing
`app.py` is the application entry point and primary controller layer. It owns Flask route handling for the home page, student listing/search, creation, editing, and deletion. Routes accept browser form submissions, perform server-side validation, invoke persistence operations, set flash notifications, and redirect or render the appropriate page.

Core paths: `app.py`, `templates/home.html`, `templates/students.html`

#### Student CRUD Flow
The central domain object is a student record with `id`, `name`, `age`, `gender`, `course`, `email`, and `phone`, stored in the MySQL `students` table. Browser actions flow from add/edit/list pages to Flask handlers, then through the database layer for INSERT, SELECT, UPDATE, or DELETE; successful and failed operations return to page flows using redirects and flash messages.

Core paths: `app.py`, `database.py`, `templates/add_student.html`

#### Persistence Boundary
`database.py` encapsulates connection to the external MySQL service and is the repository’s database integration boundary. The deployment requires a reachable MySQL instance and a pre-created `student_management` database with its `students` table. Database credentials/configuration are materially coupled to this layer; `config.py` may provide application-level configuration.

Core paths: `database.py`, `config.py`, `README.md`

#### Server-Rendered Presentation
Jinja-rendered templates define the user-facing page states: landing page, student collection/search view, create form, and edit form. Templates are the interface boundary between Flask-provided data/flash state and browser interactions. The listing page is the likely integration point for search and per-record edit/delete controls.

Core paths: `templates/home.html`, `templates/students.html`, `templates/edit_student.html`

#### Frontend Assets and Interaction
CSS is organized per page and delivered as Flask static assets. Client-side JavaScript, where used, supports UI behavior such as delete confirmation and search interaction, while validation and persistence authority remain server-side in Flask.

Core paths: `static/css/home.css`, `static/css/students.css`, `static/css/add_student.css`

#### Operational Boundaries
The system is a local or server-hosted Flask process backed by MySQL; it has no indicated authentication, API layer, queue, object storage, or external SaaS dependency. Main trust boundaries are browser-to-Flask HTTP requests and Flask-to-MySQL database access. Authentication, authorization, pagination, exports, and advanced student-related modules are explicitly future work rather than current architecture.

Core paths: `app.py`, `database.py`, `README.md`

### Flask Application

- [Flask Entry & Routes](https://github.com/sachin-54/studentmanagementsystem/blob/main/app.py): application controller · Handles home, list/search, create, edit, and delete routes. · `app.py`
- [Validation & Flash Flow](https://github.com/sachin-54/studentmanagementsystem/blob/main/app.py): request handling · Validates forms and redirects with operation notifications. · `app.py`
- [Application Config](https://github.com/sachin-54/studentmanagementsystem/blob/main/config.py): configuration · May provide application-level settings. · `config.py`

### Persistence

- [Database Integration](https://github.com/sachin-54/studentmanagementsystem/blob/main/database.py): repository boundary · Encapsulates MySQL connections and CRUD operations. · `database.py`
- **MySQL Service**: external database · Requires the pre-created student_management database.
- **students Table**: student records · Stores id, name, age, gender, course, email, and phone.
