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

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.
