because the system is designed to be able to handle complex queries for information much faster than are traditional databases, designing and implementing such an attack becomes more difficult and complex (Warigon, 1997). At the same time, the ease with which information in a data warehouse can be manipulated creates more significant problems than a traditional database should unauthorized access be obtained (TechFaq, 2010). While no database or information system could possibly have all necessary security precautions embedded within the structure of its basic operations -- i.e. storing, classifying/analyzing, and retrieving data -- as it is simply not in the nature of an information system to provide such security, data warehouses are at a special level of risk due to the organization of data and the speed at which it is processed (TechFaq, 2010; Warigon, 1997). Building effective...

This makes data warehouses not only some of the most efficient and effective information tools available to many corporations, but also among some of them more secure when properly maintained (Nishith, 2005; Warigon, 1997).
