Dr. Sargent,

My program currently deletes all of the review records in the DB before fetching a new data and storing them in a DB.
Should I alter the code so that the fetcher will only store the data that is newly encountered (from the DB's perspective)?

Please let me know if you can. Thank you,

We are only using the DB to store the latest weather records, as a way of caching them. So I would delete old records before adding new ones. You could go the extra step, but since we are only storing a dozen or so records with each update, I don't think there will be any performance impact. 

I see. Thank you for your reply!
