What are Determinants in Cognos?

Determinants are one of the features introduced in Cognos 8 that is designed to offer control over the granularity that is similar to Dimension Information in Cognos. Determinants are closely related to the indexes and keys in the database. There are no hierarchies in the determinants, but the order through which the determinants are specified, they are evaluated in the same way.

It can define a particular set of database columns that identify the set of columns, data or no unique set within that particular data. Determinants also join at different levels of granularity on every single query subject.
