performace of query

[Former Member]

HI All,

I am working on BO XIR3.1. i want to know about the query performance between 2 scenario -

1) i have 4 dim obj with aggregate object in single query so all 4 object come under group by i have created 4 table in report with individual object & aggregate table and need to show group by with dim object into each table.

2) i am creating 4 dataprovider with individual dim object and agg. obj.

When data will grow can be million records as per performace wise which scenario will work fast.

Regards,

Thanks Stratos for giving ANS,

but in 2nd scenario also inspite of having diff. data provider for grouping ..in the report label we have to show groping on dim. column bz we have to show data like that will it be any performace issue for this.or bz of query already doing group by as per agg. measure it will not effect on performance which using group on report also...

Ex-

A 56

A 72

A 5

B 8

B 89

.

.

after groupby

56

A 72

5

8

B 89

same way 4 table into same report..

Hi

I would go for scenario 2. This way you avoid having your WebI server do the grouping. Depending on your number of rows (you are talking about millions of rows) this can be really critical for the performance.

Stratos
