Note that even though partial updates sounds like what you should do (because only part of your data has changed), unless you are dealing with lots of data, just re-adding everything (if possible) can be plenty fast. So before you write complex code to construct partial updates from your csv files, benchmark to see if it's really a problem. For example, we used to fully import a DB (~800K records) always because it'd take around 5 minutes - there was no need to write a delta system.
