Data Processing

Data processing:

Real - life scenarios:

Someone wants to buy a book from Amazon - Transaction processing – because computers are constantly making sure that the details are always up to date and as accurate as possible. So if an item goes out of stock, the website is updated immediately. There is also a database containing all the fundamental information that is needed, such as a list of stock or students. Another example of transaction processing is when banking online.

Someone wants to buy a ticket for V festival – Real time processing – because the database behind the transaction is always updated immediately, so the data is as accurate as possible. This is important for bookings so that things don’t get double or over booked. Another example of this is using PayPal and eBay.

Someone wants to pay their gas bill – Batch processing – because when they pay their gas bill the amount of gas they have used will need to be measured, therefore data is being collected together, it is then fed into a computer system so it can be processed. Human involvement is not necessary. This batch processing can also be used fo preparing electricity bills, processing checks and exam results.
