Analysing

Analysing is an information process that looks for patterns or meaning in data. It's role is to transform data, a collection of raw facts, into something useful that we call information. The main problem with describing analysing as a process is that it can produce information or just more data. The distinction between what are data and what is information is a personal one. Operations such as sorting and searching, creating graphs and charts, performing calculations or just simply adding descriptions are all techniques used to analyse data. In all these operations, the original data are unchanged. Advanced analysis methods, such as modelling and simulation, often require the information system to have a large amount of storage and a fast processing system to perform all the necessary calculations and data comparisons.
