Q1.
Determinants define functional dependencies between query
items. It is used to avoid double counting of data is
denormalized data sources. Determinants are used to
-Add information about dependencies between columns to avoid
double-counting.
-Specify the granularity of a de normalized query subject to
control grouping and double-counting.
-Uniquely identify the row of data when retrieving text blob
data.
-Override the determinants imported from the data source
that conflict with relationships.
e.g.
Determinant and Dependent
The terms determinant and dependent can be described as follows:
1. The expression X Y means 'if I know the value of X, then
I can obtain the value of Y' (in a table or somewhere).
2. In the expression X Y, X is the determinant and Y is the
dependent attribute.
3. The value X determines the value of Y.
4. The value Y depends on the value of X.

Answer / ssr
Let us understand the determinants in simplest terms.
Company CEO Empl
-----------------------------------------------------
Ennov Vijay Vishwas
Ennov Vijay Mritunjay
Ennov Vijay Farrukh
Company Revenue
---------------------------------------
Ennov 500000
Carrot 400000
When above 2 tables are joined on Company field and you
bring following items in the query Company,CEO, Revenue. The
following will be the output
Company CEO Revenue
-------------------------------------------------
Ennov Vijay 500000
Ennov Vijay 500000
Ennov Vijay 500000
You got three rows because Ennova had three employees, here
cognos was not able to understand that granulirity of both
these tables was different. You have to defined it
explicitely and end product of this is called DETERMINANTS.
Here in the first table you have to define 2 determinants
CEO and Company and and check the check box of group by. Now
when you run the query in cognos you will find that
repeation is not there
