Last year, at about this time of the year, I was well involved in the process of writing the book Pentaho Solutions: Business Intelligence and Data Warehousing with Pentaho and MySQL" for Wiley.

Loading a dimension table with SCD1 and SCD2 attributes

Jos, my co-author for the "Building Pentaho Solutions" book just pointed me to a recent article by Jeff Prenevost entitled "The Problem with History".AbstractJeff's topic, loading a hybrid Type 1 / Type 2 slowly changing dimension table is related to data warehousing but maybe of interest outside of that context as well.

As it turns out, the particular problem described by Jeff is non-trivial, but can be solved quite elegantly in a single SQL statment. This may be a compelling alternative to the multi-step, …
