🔵 Batch processing would be used if you had collected a very large amount of data offline and need to now process it all in one go
🔵 Transaction file of hours worked is kept
🔵 Master file of workers details/rate of pay per hour
🔵 Transaction file is used with master file to update master file/produce
payslips
🔵 Jobs are set up so they can be run to completion without human interaction
🔵 The input data are collected into batches and each batch is processed as a
whole
🔵 Batch processing can occur when the computing resources are less busy
🔵 Batches can be stored up during working hours and then executed during
the evening/whenever the computer is idle
🔵 Batch processing is particularly useful for operations that require the
computer or a peripheral device for an extended period of time
🔴Real-time processing would be suitable for controlling the rockets
🔴Real-time processing causes a response within specified time constraints
🔴Real-time responses are in the order of milliseconds, and sometimes
microseconds
🔴Real-time means that the inputs are processed and produce an output
which in turn affects the input
🔴Controlling rockets often involves the use of sensors and control systems
🔴A computer system used for real-time processing is often used 24 hours a
day for the same task
🔴Real-time data processing gives the scientists the ability to take immediate
action for those times when acting within seconds is significant
🔴If a rocket is off course for just a short period of time its speed is such it
would be off course by a large distance
🔴If the rocket veers off course the computer would immediately fire engines to correct it.
Real-time processing requires/batch processing does not require constant use of the computer when it might be needed for
other tasks.
Real-time processing requires immediate processing of data which is unnecessary with payroll.
Hours worked would only be known at the end of each day so there is no point in using real-time processing.
The payroll only needs to be run at the end of the week/month so real-time processing is unnecessary.
Real-time processing does not usually involve the processing of large volumes of data such as running a whole company’s
payroll.
