About Cube design

Question

Hi,
i'd like know if in AWM I can have a single cube with multiple fact tables Fact tables share any dimension, otherwise others are specific of a single fact table (or each fact table needs a different cube) and if a member of the cube can be mapped only by one fact table and not necessarly by both.
Thanks

Answer 1

I would be able to answer well if you can you describe your facts and elaborate what you want to achieve? In earlier post I was trying to say that suppose you have a fact with dim1,dim2,dim3 with measure1 and you create one cube for it say cube1.
Now do you mean that you have another fact with dimensionality as dim4,dim5,dim6 with measure2? If yes then you should create a second cube with dimensionality as dim4,dim5,dim6 with measure2.
On the other hand if you have second fact as dim1,dim2,dim3 with measure2 then in this case you can have only one cube with two measures and the source to load the cube could look like this
create view cube_source as select dim1,dim2,dim3,sum(measure1),sum(measure2) from(
select dim1,dim2,dim3,measure1,null from fact1
union all
select dim1,dim2,dim3,null,measure2 from fact)
group by dim1,dim2,dim3
Above is my perception but I am not sure if you I really understood your question correctly. Can you elaborate what you are trying to achieve?
Thanks,
