Answer Posted / anirban pal
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.
