According to the notation in [BuG01], the data cube in figure 1 can be stated here in the form given in [BuG01, page 222-223]:
In general a dimension D with m dimension values can be defined formally as a m tuple (a sorted list of m values):
Consequently, |D| = m defines the number of dimension values of the dimension D (cf. >Startseite >Informatik >Business Intelligence >Data Warehousing >>tab: Infos).
Furthermore, a (data) cube C can be specified in the following notation:
where:
Based on this notation, the data cube in figure 1 can be generally defined as follows:
