Hi guy's, First off sorry if this is a noob question.

But I'm trying to find out more information about the hotfix_data table in 4.3.4.
I know its possible for this to overwrite data in the item_sparsed.db2. For eg to can lets say remove the cost price on a item. I'm just not sure how it does it. If anyone has any information on it or could point me in the right direction that be great.
