Obtain a logical DFD for the simple payroll system described below:

A list of employees with their basic pay is sent to a clerk. He calculates the gross pay using

standard allowances, which are known for each pay slab. Deduction statements such as loans

repayments, subscription to association etc. are send to another clerk who matches these slips

of the gross pay and calculate the net pay. The slip is used by another clerk to write out the pay

cheques for each employee and sent to respective employees. The total pay bills are also

computed.
