I think what you want to make is a data warehouse, a big database that holds all the data from all the sources in one place.
Next you would build cube(s) off of that source. The thing to do is to massage all your data into the same format before it gets into the datawarehouse.
You say that all the databases may be one dimension, sounds to me like a terminology problem. They would all feed one data warehouse, perhaps just one cube depending on the queries you want to run, could quite easily be more. This depends on your data structure, and what you want to find out from your data.
Dimensions are the things you want to chop the data up by, eg Time, Location, Product, Customer etc
One last thing, I would recommend strongly that you use Analysis Services, the OLAP tool that comes with SQL Server 2000, as it is FAR better than the verion 7 product.
hope this gets you started
