A dimensional database is one which, rather than representing data in multiple relations (as a
relational database does), represents key data entities as different
dimensions. That is,
multidimensional database systems offer an extension to the relational system to provide a multi-dimensional view of the data (Rand). For example, in multi-dimensional analysis, data entities such as products, regions, customers, dates etc. may all represent different
dimensions. This intrinsic feature of the
database structure will be covered in depth in subsequent sections of this article.
