Hello Mahesh.
Answers below.
Remember. In all cases the dimension processing option has a direct
effect in the fact (cube) processing option.
I'm not considering the Proactive Cache option in the answers
(SSAS2k5).
What will be the best processing option under these four situations?
1.
Dimensions: addition of new members but no changes in existing members
Fact: new records but no changes in existing records.
Dimensions: Incremental
Fact: Incremental
2.
Dimension: addition of new members but no changes in existing members
Fact: new records as well as possibility of changes in existing
records.
Dimensions: Incremental
Fact: Refresh
3.
Dimension: addition of new members as well as changes in existing
members like moving under new parent.
Fact: new records but no changes in existing records.
Dimensions: Refresh
Fact: Refresh/Full
4.
Dimension: addition of new members as well as changes in existing
members like moving under new parent.
Fact: new records as well as possibility of changes in existing
records.
Dimensions: Full
Fact: Full
Will the processing option be different if the changes in existing
records are extremely rae vs very frequent changes? Any response will
be very much appreciated.
What is the volume of data to be processed?
How much time do you have to process it?
These questions will have more influence in your processing options.
Hope this help in some way.
