Wrap every activity that writes or that reads to this database in a transaction.

Reading from the database does not require disk-sync calls and wrapping them into a transaction won't help. Besides, transactions themselves don't help one bit unless you wrap multiple writes into a single transaction. (I guess you understand that but failed to say so.)
