Hi,
We have a data storage solution where we have split the storage of data by geographical region into multiple relational databases. Each database has the same schema internally and we are now looking to federate a subset of the data to give country-wide views for some key KPIs.
Rather than federating the data into another "master" database, we would like to use multi-source universes to handle unifying the data so that we can create a single report for country wide analysis. However all the literature (that I can find at least 
) talks about multi-source universes in the context of multiple databases each with different schemas. I can't find anything that describes how a universe will behave in this situation.
Has anyone any experience of trying a solution like this? Is this a feasible approach? Or will the unx not like the same schema coming from multiple databases?
Thanks!
