Thus, without concurrency control such systems can neither provide correct results nor maintain their databases consistent.
22.
We have better synchronization algorithms and fancier ( if not necessarily better ) languages with concurrency control.
23.
They are typically much more effective than applying to indexes common concurrency control methods applied to user data.
24.
Transactions provide a concurrency control abstraction for the OS, and can be used to prevent TOCTTOU races.
25.
The commitment ordering solution comprises effective integration of autonomous database management systems with possibly different concurrency control mechanisms.
26.
A major goal for distributed concurrency control is distributed serializability ( or global serializability for multidatabase systems ).
27.
Concurrency control can require significant additional complexity and overhead in a concurrent algorithm compared to the simpler sequential algorithm.
28.
These sorts of problems with shared resources need the use of concurrency control, or non-blocking algorithms.
29.
He submitted his thesis " The complexity of concurrency control for distributed databases " in September 1981.
30.
In this case we deal with distributed concurrency control of the system, and the two terms sometimes overlap.
