INTRODUCTION

The DEVRIS DIGITAL FORTRESS is a C++ portal to access and handle all types of accounts that are it the records. This portal enables us to access the employee’s record as well as the customers’ record. It also helps in managing the discounts and in modifying the details of an employee or customer. It is user- friendly portal which can be easily handled by anyone. One can easily add an account, modify it, delete it, etc.

I hope you’ll all like this portal.

Thank You.
