Continuous scattering and non-atomicity of a face-homogeneous random walk.
Although implementations vary depending on factors such as concurrency issues, the principle of atomicity i.e. complete success or complete failure remain.
However, if a failure occurs, then due to atomicity, the amount will either be transferred completely or will not even start.
Atomicity may be achieved by using a machine instruction that is able to read, modify and write the semaphore in a single operation.
Both are done to ensure atomicity and durability of transactions.
All "distributed transactional systems" rely on some atomic commitment protocol to coordinate atomicity (whether to commit or abort) among processes in a distributed transaction.
An example of atomicity is ordering an airline ticket where two actions are required: payment, and a seat reservation.
Transaction consistency is also frequently referred to as atomicity.
In write ahead logging, atomicity is guaranteed by copying the original (unchanged) data to a log before changing the database.
Finally, atomicity itself relies on durability to ensure the atomicity of transactions even in the face of external failures.
The atomicity of these elements is not specifically mentioned and it appears that they were actually taken to be continuous.
Atomic commitment protocols are intended and designed to achieve atomicity without considering database concurrency control.
Atomicity is commonly enforced by mutual exclusion, whether at the hardware level building on a cache coherency protocol, or the software level using semaphores or locks.
In other words, atomicity means "indivisibility" and "irreducibility".
We simply allow interleaving of atomic actions, whose atomicity plays a vital role in the system.
