Libraries order items, check out items to patrons, process returned items, and organize items on shelves. What data management solution should a library use to track this information?
a spreadsheet
a database
a flat file
a filing cabinet

I believe the answer is spreadsheet, correct me if i’m wrong

Same issue happened to me i had 4/5 and suddenly they went down to 3/5 .the reason must be that the question u recived a brainliest answer mark, was deleted by a moderator. they can delete a question for some reason if it isn't complete or has been reported. so there for that is most likely the reason.best of hope u earn another one
