HI All ,
Can you please help me with , what is the best table structure for to build a report on Qlikview , How my Dimension and Measures should be arranged(in columns , rows ) , i find that it is good to have all dimensions in rows , so that we can do set analysis easily
is my perspective correct , kindly hep me with documentation on this perspective
Thanks,
Sai
Your question is rather general, in my opinion it all depends on the hierarchies in the data you are modelling (fi: cities). With limited different dimensions with no hierarchical relation you could do it like you describe, otherwise I would suggest to use different columns for different hierarchically associated data (fi: continent, land, city)
Hi Sai,
To begin with have a look at this document which might help:

it will depend on how many Fact tables you have.
Best is a single table, but most aim for a star structure.
Often the model becomes a snowflake, if it's more like a a blizzard, you may have issues and need to review it :-).
That said the number of rows and data variability is also a factor.
As the data volumes get bigger, you should aim towards a simpler model.
