> Database issue. You just go there and change the data
I have heard stories of how very large financial institutions never ever delete a database column from a table, they just keep adding columns. They will not delete a data column for the very real fear that mission critical applications will stop working properly or fail silently.

The cost of carrying a hundred unused columns around forever is negligible compared to the cost of deleting one that turned out to be still used.
