n addition to dimension member names, locations, and relationships, Essbase stores characteristics, called attributes, about members. For example, the Product dimension indicates that in Women's Apparel, Shirts and Blouses, there is a cotton T-shirt; an attribute indicates that the cotton T-shirt is red, cyan, lime, or pink. Essbase does not store data for attribute dimensions as part of the multidimensional database but instead dynamically calculates it upon request. Attribute dimensions are displayed in dimension hierarchies, in the same manner as other dimensions, despite their data being stored differently.
