Summary of concurrency control

The concurrency control of database is based on transactions
Database concurrency control usually uses blocking mechanism
Basic blockade
Multi granularity blocking
Live and dead locks
Correctness of concurrent transaction scheduling
Serializability
The correctness of concurrent operation is usually guaranteed by two-stage locking protocol .
The two-stage locking protocol is a sufficient condition for serializable scheduling , But not necessarily
Conflict serializability
Other concurrency control mechanisms
Timestamp method
Optimistic control
Multi version concurrency control
