Commercial Data Processing

CDP is all about how large companies deal with and process a lot of data. Like the Lottery, Airports, Morrisons, Spar! (Yes, they do exist!)

Why do we need Computers and CDP
There is a lot of data (Large Volume of documents)
Faster to search through than manual (imagine trying to find a lottery winner from 32 million tickets sold)
Provides high speed access to data (trying to book in at an airport for)
Handle repetitive tasks (imagine having to check EVERY lottery ticket!)

Advantages of Using Computers
Orders processed much more quickly
Computer checks built in so errors less likely
Maintain contact with a large number of people
Easily keep information up to date
Single Entry Multiple Use
One department enters information all departments can access the information

Data and Information

Information(for people) = data(for computers) with structure
