Describe the features and functions of information systems and explain how an organisation could improve the quality of its business information
Input – input to information systems works in two ways. The first way is detailed data. This is sorted and processed and makes the basis of the output from the system. The second part is when the user tells the system what sort of analyses they want form the system.
Storage – Data should be stored at the most detailed level. IT departments will have to make sure to have backups of the data in case anything happens to the original copies.
Processing - Processing is the method that turns data into information. There is simple and complex processing. Simple processing is adding all the items sold by a supermarket and producing totals. Complex processing is a computer program that does complex calculations and makes assumptions about missing data.
