I read a book by Brian Larson which says that Unified Dimensional Model or UDM, which was introduced with SQL server 2005 eliminates the need for ETL and creatin. It achieves this by querying the OLTP systems directly, like a database view does.
Of course, ETL jobs, particularly SSIS jobs, still appear in job boards, so they are probably not dead yet.
So, my question is that will UDM really kill ETL and ETL jobs in the near future (5 years) ? If not, then why ?
