Linux Laboratory

Problem Overview:
The general attributes are all required and are stored in a separate file with a structure similar to that of the attached GAttributes.txt file. The description of each of these attributes is:
• Employee ID: the ID of the employee. This attribute must contain only numbers with five digits and must be unique.
• Name: the name of the employee. This field must contain only characters.
• Marital status: this field has two possible values: single or married,
• Number of Childs,
• Gender: this field has two possible values: male or female,
• Contact information: {Email, Mobile number, Fax},
• Type: this field has two possible values: academic or administrative,
• Department: the place where the employee works for example computer engineering department,
• Basic salary: the basic salary of the employee,
• Vacation = {key: year: value = number of days}.
The data for the vacation attribute is stored in a separate file with a structure similar to that of the attached Administrative.txt file.
• Experience= {key: year-semester: value = list of all courses taught in that year-semester}.
The data for the experience attribute is stored in a separate file with a structure similar to that of the attached Academic.txt file.
Scenario:
• First, the program will ask to enter the name of the employee record file and raise an error if the file didn’t exist.
• Then, the program will print the available list of options as following:
1. Add a new employee record: here the program must ask to enter new record for an employee that consists of all general attributes only. The program must check the entered data.
2. Update general attributes: here the system must ask for employee ID and then the name of the general attribute/s and finally the new value. The program must raise an error if the ID does not exist and must also check the entered data.
3. Add/update administrative employee attribute: here the program must
b. For administrative employees, the program then asks for the data of the vacation attribute including the year and number of vacation days. If the year is already in the employee Vacation attribute, the project should update the number of days. Otherwise, it will add a new {key: value} to the Vacation attribute.
4. Add/update academic employee attribute: here the program must
d. For academic employees, the program then asks for the data of the Experience attribute including the year, semester, and courses. If the year and semester are already in the employee Experience attribute, the project should update the list of taught courses in that semester. Otherwise, it will add a new {key: value} to the Experience attribute.
5. Employee’s statistics: the program must display the following information:
• Number of academic employees,
• Number of administrative employees,
• Percent of Full-time employees,
• Number of Male employees,
• Number of Female employees,
6. Salary statistics: the program must display the following information:
• Average academic employees’ salary
• Average administrative employees’ salary
• The names (full name) of the employees who have salaries greater than a user defined number. Here the program must ask user to enter this number. Note that the final salary is computed as:
Final salary = basic salary + 20 if the marital status is married + 15*number of Childs – 12 * (1 + (1 + number of Childs) if marital status is marid and joint the health insurance)
8. Courses statistics: the program must display for each course the following information:
• Number of times the course is offered,
• Number of academic employees who taught this course.
9. Administrative employees’ statistics: the program must display for each administrative employee the following information:
10. Academic employees’ statistics: the program must display for each academic employee the following information:
Note that, after choosing and execute the option, the program will print again the list of options.
Submissions:
• You need to submit the code in .py format. If you made different files, you need to create a module and import them.
• Provide screenshots for each option
• Provide descriptions of the used data structures with clarifications (Why did you use it here?).

Important notes:
• Write the code for the Python program to satisfy the requirements described above.
• You must use functions (at least one function for each option).
• You must use OOP concepts (classes, inheritance …). You must create a class for the general attributes and use inheritance to create classes for administrative and academic employees.
• You must organize your project in modules. I. e. have each class and the main function in separate modules (python scripts).
• Make sure your code is clean and well indented; variables have meaningful names, etc.
• Make sure your script has enough comments inserted to add clarity.
