ICT

• PAYROLL
• Payrolls are used to manage
• wages and salaries of the employees.
• There is a lot of data to
• put into account and may need a few days or processing.
• Workers are paid in arrears—they are paid for the week before the one they have just worked. This
• means that the payroll system has one week to process the payroll data.

ICT

• Swipe cards
• Each employee has a swipe card that carries:
• ·
• A unique employee number
• ·
• Clock-in time
• ·
• Clock-out time
• This information is passed onto the ICT systems every time the
• card is swiped.

ICT

• Validation
• Validation checks are made
• on all data that passes through the system.
• This is to ensure that the
• data is appropriate and accurate.
• The data can be checked
• against a table of known employees (table
• look-up); the clock-in and clock-out times are of a reasonable range (range check) e.g. the clock-in time
• must be ‘less’ than the clock-out equivalent.
• Invalid data is corrected
• before it is processed any further.
• Valid data is processed onto
• the transaction file [abbreviated
• t-file] (this data changes often).

ICT

• Master files
• Data that does not change
• frequently is saved on an old master
• file [abbreviated m-file], which every employee has one of. It contains:
• ·
• Employee #
• ·
• Employee name
• ·
• Address and other contact details
• ·
• Hourly rate of pay
• ·
• Details of the tax to be paid
• ·
• Cumulative totals of the tax paid during the current
• tax year
• ·
• Employee’s bank account details
• For every employee, the
• record on the transaction file and the corresponding record on the master file are
• quickly matched so that the data is available when the payroll program runs.
