Data Processing

Types of Processing Batch processing Interactive processing Real Time processing

Types of Processing Printing interims Booking tickets online ABS

Batch Processing: data can be collected over a period of time when all data collected it is processed at the same time -as a ‘batch’ data is processed at an off-peak period -when there is less demand on the processor -less disruption to the daily work schedule -system & peripherals available when most needed does not need staff intervention suitable for situations where there is a lot of similar data to be processed & the processing can wait: -cheque processing in a bank, gas bill printing, payroll processing not suitable where the data must be processed instantly -data is not up to date until processing completed

Interactive Processing: accepts and responds to input from user -direct user interaction whilst a program is running “question and answer” between user and computer computer gives the user an immediate response

Interactive Processing: Examples: Booking concert tickets Ordering books online Handling bank accounts Booking a holiday -fill in a web form, -submit it -site informs you of the room you have booked.

Interactive Processing: this system allows customers to check whether the goods they want are in stock. when they enter the item number they wish to purchase, the system will immediately tell them whether the item is available.

Real Time must respond to events with no discernible delay responds immediately to the data entered used where response time by the system is critical -where delays in processing would prove unacceptable used for control systems -traffic lights, air traffic control, aircraft navigation used for embedded systems -systems within another application, -e.g. cars and mobile phones

Real Time Examples: Traffic lights Heart rate monitoring Aircraft control Computer games Controlling robots
