The data Processing Cycle and processing methods

Extracts from this document...


The data Processing Cycle and processing methods Data Handling All organisations and businesses no matter how big or small they are have to process data. Sales data, Wages, Invoices, and Purchasing are the four most common processing methods. They are two types of ways which data can be processed, Firstly is can be done by paper and pen this is called manually. This is not I good way to process data as it's time consuming and errors can be made. Small corner shops can use this method as they don't have to process much data. But it is not a good idea if big companies use this method as it would take too long and the chance of making mistakes increases. The second method is by using computers (electronically) most businesses use computers to process data. The main reasons for this is because computers are affordable for most businesses. And they can process data more efficiently and quickly. So computers have changed the way businesses operate as they are more reliable and they can process large amount of data within minutes. The diagram below shows the data processing cycle. ...read more.


But there is a lady in Liverpool and London wanting to go on that holiday. So they go into a Thomas Cook branch wanting the Barcelona holiday. The lady in London finishes booking the holiday and the staff confirm the booking this is then automatically updates the main computer where all the staff can see that there is no more flights. Because the lady in Liverpool was looking at holiday brochures and decided to look for other holidays she missed out on the Barcelona deal. My second example is ATM machines when I person takes out money at a ATM machine it has to be updated immediately so the same person can not take out what they don't have again. Also they can receive a statement with the latest information on it such as how much money they have left in their account. Real-time process control This means that the information is updated straight away (opposite of batch processing). Computers have to be fast and accurate to get the best results. When a user uses a ATM machine the input will be processed and updated quickly. Information processing in real-time This is also done quickly a good response time is between the entry of the transaction to processing of the data and the computers response. ...read more.


So the time that staff have saved can be used elsewhere. Also other electrical methods would helpful for example in a larger organisation E- mail could be useful as it's free and quick. Type of organisation Application 1 Application 2 Sales Payroll Larger organisation e.g. StayBrite Windows Online = get information straight away. Batch = done weekly or monthly Small corner shop Batch = done every two or three days Batch = done weekly or monthly The table above shows two different applications one is Sales and the other one is Payroll. Both of my chosen organisations use these applications. The two organisations that I have chosen are StayBrite Windows and a Corner shop that is privately owned. The sales department at StayBrite Windows has to be online because if a customer wants to pay for a conservatoire the sales department have to check with the accounts department if there credit history is good enough for the sale to go ahead. As for the corner shop most of the time it will deal with cash. So there is no need to be online. The second application is payroll. Both of my companies use Batch processing for payroll. Because it is not necessary to update information straight away. The information of the worker/workers will be collected over a period of time. 1 Almir Dautovic ...read more.
