From this point on, an important process is represented by storing multidimensional data in datawarehouses, in order to be processed and analyzed with the purpose of obtaining information which can be used for decision making in various activities. Specialty studies show that most data is not useful for the purpose it has been collected because of both the lack of quality and incorrect techniques of manipulating this data.
