Concurrency Control

The simultaneous occurrence of two or more operations is called concurrence and the situation is called concurrency. In concurrency, the function of one operation can affect the function of the other and put data integrity at risk. Hence, management for the control of concurrency is required. The management or controlling system in the Database Management System (DBMS) that coordinates concurrent access is called the concurrency control system.

Question

Implementations of database systems frequently employ strict two-phase locking. When compared to other protocols, why is this one so widely accepted?
