Nowadays the importance of information exchange, accumulation and processing is increasing in modern business.

How these amounts of data are formed, are they really necessary, and how can they be disposed? Sooner or later any company's management faces these questions because the storage of information requires certain expenses, which increase depending on the growing amount of data.
