Data Processing + information needed by businesses

Data Processing
Scenarios:Someone wants to buy a book from amazon.
Transaction Processing – because computers can make sure that details are always up to date and as accurate as possible so therefore if there is a change in price or the product has gone then it will update the website immediately. There is also a database containing all the fundamental information that is needed, such as a list of stock etc. Another example of this is moving money from one bank to another, this may not be done until the end of the day etc.

Someone wants to buy a ticket for the V Festival.
Real-Time Processing – because there is a database that can adjust and update any changes immediately to this type of transaction. This is very important with bookings as if a place or seat is booked, then the next customer cannot book the same thing.

Someone wants to pay their gas bill.
Batch Processing – because a set of data is collected together (how much gas they have used), it is then fed into a computer system to process it. Human involvement is not necessary. Another example of this is a teacher and marking their students work.





Types of Information needed by Businesses

Finance – Any department within a company/organisation needs budgets to prevent them from becoming bankrupt. This is because if a company spends more than they earn they get themselves into debt. It is important that every organisation, even those that are non-profitable such as schools and hospitals, keeps track of their finances.

Production
Many different businesses sell a product, in the process of making the product there is the production process, this is either mass production, batch production, continueoues production or one-off production, with a good IT system the production is kept going and the supply under control if this supply was not kept under control then for example a car manufacturer may run out of components and th eproduction line will come to a standstill, either though the workers are getting paid for this.Batch Production- is when there is a small amount around 1000 being producedMass production- when there is huge amount being produced like car manufacture like FordOne-off production- is when a product is made only once like a conecpt gadgetContinueous production- is when the production line is running 24/7 like making aluminiun cans
