In a distributed environment an atomic commitment protocol, typically the Two-phase commit ( 2PC ) protocol, is utilized for atomicity.

The advantage is that the atomicity of the Invoice ( conceptual ) and the Invoice ( data representation ) are one-to-one.
25.
In fact if you've got a ) and b ) then it seems you've got ( the effect of ) atomicity.
26.
The safety net that PSO provides is similar to TSO s, it imposes program order from a write to a read and enforces write atomicity.
27.
Atomicity is a guarantee of succeed-or-fail definition they either successfully change the state of the system, or have no apparent effect.
28.
Atomicity is often enforced by mutual exclusion, whether at the hardware level building on a cache coherency protocol, or the software level using locks.
29.
Improper synchronization can lead to multiple failure modes including loss of atomicity, consistency, isolation and durability, deadlock, livelock and loss of serializability.
30.
From a programmer s perspective all these models must maintain the illusion of write atomicity even though they allow the processor to read its own write early.
