              Abstract: This article presents the evolution of databases   from classical relational databases to distributed databases and   data warehouses to fuzzy databases used in a production   enterprise. This paper discusses characteristics of this kind of   enterprise. The authors precisely define centralized and distributed   databases, data warehouses and fuzzy databases. In the modern global   world, many companies change their management strategy from the one   based on a centralized database to an approach based on distributed   database systems. Growing expectations regarding business   intelligence encourage companies to deploy data warehouses. New   solutions are sought as the demand for engineers' expertise   continues to rise. The requested knowledge can be certain or   uncertain. Certain knowledge does not any problems and is easy to   obtain. However, uncertain knowledge requires new ways of obtaining,   including the use of fuzzy logic. It is from where the fuzzy   database approach takes its beginning. The above-mentioned   strategies of a production enterprise were described herein as a   case of special interest.
