Merging dimensions from multiple data providers74
all the data providers synchronized through the merged dimension in the same block as
the merged dimension.
Which dimensions do you merge?
The only restriction that Web Intelligence imposes on merged dimensions is that they must
be of the same data type: for example, character data. But it does not make sense to
merge unrelated dimensions even when their data types are the same. For example, it
does not make sense to merge a dimension containing customer names with a dimension
containing sales regions.
Merged dimensions often have the same name in both data sources, but this is not
obligatory. It can make sense to merge dimensions with different names if they contain
related data.
To merge dimensions correctly you need to be aware of the semantics of the data (what
the data refes to) in the different data sources. The dimension data types and names are
an approximate guide only to dimensions’ suitability for merging.
Merging dimensions
To merge dimensions:
1. Click Merge Dimensions button on the toolbar.
The Merge Dimensions dialog box appears.
