## Overview

GLOBIT is a PHP/MySQL HR information system. Users enter through the web front controller, which routes authenticated and role-checked requests to controllers; controllers coordinate domain models and render views or produce exports. Its documented core workflow covers employee/service administration, attendance check-in and approval, leave requests and approval, and dashboard reporting. The README also describes payroll, training, and mobile capabilities. Some of these modules are represented from the tree and index references only; unsampled implementation details and links are therefore omitted.

Main entry points: [`core/Router.php`](https://github.com/ezechielitewe18/sirh/blob/main/core/Router.php) (Request router), [`models/EmployeeModel.php`](https://github.com/ezechielitewe18/sirh/blob/main/models/EmployeeModel.php) (Employee records), [`controllers/DashboardController.php`](https://github.com/ezechielitewe18/sirh/blob/main/controllers/DashboardController.php) (Dashboard), [`core/Model.php`](https://github.com/ezechielitewe18/sirh/blob/main/core/Model.php) (Model base)
