Determinants define functionality dependencies between Query Items. Use determinant to avoid double counting in de-normalized data

=> Determinants reflect granularity by representing subsets or groups of data in a query subject and used to ensure correct aggregation of this repeated data.
=> Determinants are most closely related to the concept of keys and indexes in the data source and are imported based on unique key and index information in the data source.
=> By modifying Determinants, you can override the index and key information in your data source,replacing it with information that is better aligned with your reporting and analysis needs.

Answer / madhoo
Determinants are used for to improve the query performance
these are like .... 1. Computer system and network capacity
2. Schema design
3. Database objects
4. Best practices for writing queries
5. Physical storage layout
6. Parallel query and Red Brick Warehouse configuration
computer host loaded correctly and network traffic problem
should be overcome....
A well designed Schema has most effect on query performance...
Database object give good performance .....those are Indexes
and predefined objects...
There are so many ways to write query on a logic...but with
the help of best practices only we can write well
performanced query.
