                string sqlEmployees = "SELECT NAME,DEPARTMENT,SALARY FROM EMPLOYEES";
                dEmployees = SqlDataBase.ReturnDataTable(sqlEmployees);

                //Fill the first generic List with the DataTable values
                DataFiller<Employee> dtfEmployee = new DataFiller<Employee>();

            //Linq Dummy Example
            Employee employee = (from e in Employees
                    where e.Name == "Mary"
                    select e).First();

            Console.WriteLine("The salary is: " + employee.Salary.ToString());

            Client client = (from c in Clients
                             where c.Country == "Polony"
                             select c).First();
