First, the transactions in SQL
Concept: A thing is a mechanism, a sequence of operations that contains a set of database operations commands that either execute all or do not. A transaction is an inseparable unit of work logic. The transaction is used as the smallest control unit when concurrent operations are performed on the database system. Multi-User Login system is suitable for using transaction mechanism.

. Therefore, we can distinguish different operating systems by analyzing different protocol stacks. As long as we establish a database corresponding to the protocol stack and the operating system, we can accurately identify the operating system. Currently, using this technology to identify operating systems is the most accurate and scientific. Therefore, it is also known as "fingerprint technology" for operating systems ". Of course, the ability and accuracy of identification depend on the datab
