There is also a different school of thought (only for Calendar Dimension) where instead of using sequential keys, replace it with a smartkey in the format of YYYYMMDD. I can appreciate this design since Calendar Days are always unique and sequential. Also note that this is the BASE CALENDAR, there are no Fiscal Attributes at all.

I read Gary Nissen's article, 'Is Hand-Coded ETL the Way to Go?', with interest.

Given that this was written nearly six years ago, I wonder whether the position has changed i.e. whather ETL tools are now more strongly recommended ober hand-coding.

The reason to purge is that no personal data can be kept after 4 years, but the users would still want to see counts/facts by no identifying data. For example i couldn't keep a name, but i could keep the gender or employer. Is it best to do this by depersonalising data e.g. setting certain column to NULL after a number of years, or adopting an aggregate strategy. The data volumes are not huge, but if i go ...
