A
access permission
A privilege that permits the access or use
of an object.
alias An alternative name used instead of a
primary name.
attribute
1. In relational models, a query item that
is not a measure or identifier. When a
query item is an attribute, it is not
intended to be aggregated, or used for
grouping or generating prompt pick lists.
2. In dimensional models, a property that
provides qualitative information about
members of a level in a dimension. For
example, the Store level within the
Retailer dimension might have properties
such as address or retail space. In general,
dimensional attributes do not have
measure values or rollups associated with
them, but are used to locate or filter
members.

model objects.
