Excuse me, can I delete the abnormal operation of the hotel management system?

All operation records can be deleted, but if the software itself is deleted, there will be records.

Then how to delete the unrecorded is to operate in the background server database. This is unrecorded, and there is no way to recover it if it is directly dropped.

If you don't enter the background database, then all operations are recorded. This is also a software must have.
