Company Data Analysis with Prolog

Overview

This Prolog program provides a simplistic model for representing and querying data related to employees of a company. It includes functionality to query basic employee information, such as wage and family status, and calculate benefits based on marital status and the number of children.

Files

• company.ecl: Contains the Prolog code with predicates to manage and query employee data.

Features

• Employee Data Representation: Represents basic data of employees, including name, position, wage, marital status, and the number of children.
• Wage Query: Allows querying an employee's wage.
• Single Parents Query: Identifies single employees with one or more children.
• Benefit Calculation: Calculates the benefit amount for an employee based on their marital status and the number of children.

Predicates

wage(Empl, Wage)

• Description: Retrieves the wage of a specified employee.
• Arguments:
  • Empl: Employee's name.
  • Wage: Wage of the employee.

single_with_children(Empl, N)

• Arguments:
  • Empl: Employee's name.
  • N: Number of children the employee has.

Usage

To use this program, you must have a Prolog interpreter installed on your computer. Once installed, you can load the program by navigating to the directory containing company_data.pl and running the following command in your terminal:

swipl -s company_data.pl

After loading the file, you can query the predicates directly in the Prolog environment. For example:

?- wage(john, Wage).
?- single_with_children(Empl, N).
?- benefit(Name, Wage, Benefit).
