Project Module: Sales Management System

Overview

This project simulates a sales management system. It generates random input data for salesmen, products, and their sales, then processes this data to create summary reports.

The system is implemented in Java and follows a two-class design:

1. GenerateInfoFiles.java → generates pseudo-random input files
2. main.java → reads input files and generates sales reports
