- Employee profiles
- Attendance
- Leave requests
- Shift schedules
- Recruitment
- Payroll
- Performance reviews
All data is stored securely in a centralized database.
Step 2: Workflow Automation
The system automatically triggers predefined workflows.
For example, a leave request moves from employee to manager approval, updates leave balances, and shares the information with payroll without manual intervention.
Step 3: Data Processing
The business logic layer processes information according to company policies.
It automatically handles:
- Working hour calculations
- Overtime
- Leave deductions
- Payroll
- Attendance updates
- Employee record changes
