DATA AND INFORMATION

Data
Think of data as a "raw material" - it needs to be processed before it can be turned into something useful. Hence the need for "data processing". Data comes in many forms - numbers, words, symbols. Data relates to transactions, events and facts. On its own - it is not very useful.
example:1. Transaction value (e.g. £55.00)
             2. One subject term marks (English)
Information
Information is data that has been processed in such a way as to be meaningful to the person who receives it.
example: 1. Total transaction value of the month
              2. Total marks of the students in a classroom
