Employee Database System (100 points)

You are tasked with writing a program that simulates an employee database system. The

project serves two main purposes: to provide practice in writing programs that manipulate

strings, data structures, and files, and to apply sorting and searching algorithms.

The computer first displays a login form. There are two user types in this system:

- Admin

- Users

If the user enters “admin” as username and “admin123123” as password, the system will

show the admin menu. Else, if a normal user logins, a different menu will be shown.

If any user inputs an incorrect combination, the system should display “Incorrect Username

and/or Password”. The user is not allowed to enter more than 5 wrong combinations.

Otherwise, the menu of the system will be displayed.

The System

Your job is to write a script that handles the user interaction component of the system. To

solve the problem, your program must be able to:

● Read one text file and upload all the students into the dictionary of the system

● Implement the basic control structure and manage the details

The file includes several users in the following format:

emp001, cdaoud, 20220802, male, 12000

emp002, manuella, 20220803, female, 1200

....

This file represents the list of employees in the company. Each line contains 5 words: employee

id, username, timestamp of joining (YYYYMMDD), gender, and the last word represents the

salary (integer). You are asked to import that file when the program starts.

The Flow of The System:

A. The employees written inside the text file are imported (loaded) into the data structure of the

program with no intervention and without letting the user know anything.

B. The program starts by greeting the user and asking for their username and password (if the

password was left empty, then it’s a normal employee)

If the user logged in is an admin, the following menu will be displayed:

1. Display Statistics

2. Add an Employee

3. Display all Employees

4. Change Employee’s Salary

5. Remove Employee

6. Raise Employee’s Salary

7. Exit

● If the admin chooses (1), the system should display how many employees are male

and how many employees are female.

● If the admin chooses (2), the system should allow the admin to add a new employee

to the system by specifying the username, gender and the salary only (the

employee id is auto-incremented and the date is automatically taken from the

computer)

● If the admin chooses (3), the system should display all the employees registered in

the system ordered by date (Today, Yesterday, etc).

● If the admin chooses (4), the system should allow the admin to change the salary of

an employee by specifying his/her Id. The system should prompt the admin for the

Employee ID and for the salary. If the employee is found, then the salary is

changed.

● If the admin chooses (5), the system should allow the admin to remove an

employee from the system by asking for the ID

● If the admin chooses (6), the system should ask the user for the employee ID and

the raise percentage (example: 1.05) and the system should increase the

employee’s salary if found.

● If the user chooses (7), the program should exit after saving the information to the

file.

If the user logged in is a normal employee, the following menu will be displayed after

greeting by the following message: “Hi Mr. Charbel” or “Hi Ms. Fatima” (pay attention to

the gender)

1. Check my Salary

2. Exit

● If the user chooses (1), the system should display the salary of the logged-in user.

● If the user chooses (2), the system will terminate and save the timestamp of the

employee's login to a new file.

After each option, the menu is displayed again. The user can use the system multiple

times.
