Micro ETL in the PowerPivot age
Although PowerPivot has many of the characteristics of an ETL tool, i.e. the ability to connect to disparate datasources, to filter that data and to transform it, it will still hit a brick wall when confronted by the typical data spewed out by operational systems. I’m sure this is by design as a sophisticated ETL tool is both complex to design and, probably even more relevant, is difficult to use.
