Question

Quizplus · Accepted Answer

Pessimistic locks are used when it is assumed that a conflict will occur, and therefore, resources are locked to prevent conflicting access by other processes. Explicit locks are locks that are explicitly requested by a process, and implicit locks are locks that are automatically set by the system. Optimistic locks assume that conflict is unlikely and therefore do not immediately lock resources.
