Design an Attendance Payroll Service
Design the backend service for an employee attendance system. The service must support the following core functionalities:
- Employee Clocking: Allow employees to clock in and clock out.
- Duration Calculation: Compute each employee's total worked duration over a defined pay period.
- Payroll Calculation: Calculate pay based on the worked duration and predefined wage rules.
- High Transaction Volume: Handle high transaction volumes efficiently, particularly during peak clock-in and clock-out times.
- Data Synchronization: Synchronize attendance data from another database or external system.
Your design discussion should cover:
- APIs
- Data Model
- Overall Architecture
- Consistency Guarantees
- Failure Handling
- Scalability strategies
- Optimization techniques for extremely high traffic scenarios.
