The past couple of decades have seen a dramatic increase in the amount of information or data being
stored in electronic format. This accumulation of data has taken place at an explosive rate. It has
been estimated that the amount of information in the world doubles every 20 months and the sizes
as well as number of databases are increasing even faster. There are many examples that can be
cited. Point of sale data in retail, policy and claim data in insurance, medical history data in health
care, financial data in banking and securities, are some instances of the types of data that is being
collected.
