In database systems, atomicity (/ ˌ æ t ə ˈ m ɪ s ə t i /; from Ancient Greek: ἄτομος, romanized: átomos, lit. 'undividable') is one of the ACID (Atomicity, Consistency, Isolation, Durability) transaction properties. An atomic transaction is an indivisible and irreducible series of database operations such that either all occur ...
An atomic system must guarantee atomicity in each and every situation, including power failures, errors, and crashes. [4] A guarantee of atomicity prevents updates to the database from occurring only partially, which can cause greater problems than rejecting the whole series outright.
Transactional NTFS (abbreviated TxF [1]) is a component introduced in Windows Vista and present in later versions of the Microsoft Windows operating system that brings the concept of atomic transactions to the NTFS file system, allowing Windows application developers to write file-output routines that are guaranteed to either succeed completely or to fail completely. [2]
A distributed transaction operates within a distributed environment, typically involving multiple nodes across a network depending on the location of the data.A key aspect of distributed transactions is atomicity, which ensures that the transaction is completed in its entirety or not executed at all.
In the field of computer science, an atomic commit is an operation that applies a set of distinct changes as a single operation. If the changes are applied, then the atomic commit is said to have succeeded. If there is a failure before the atomic commit can be completed, then all of the changes completed in the atomic commit are reversed.
Making a system linearizable is one solution to this problem. In a linearizable system, although operations overlap on a shared object, each operation appears to take place instantaneously. Linearizability is a strong correctness condition, which constrains what outputs are possible when an object is accessed by multiple processes concurrently.
Atomicity (database systems), a property of database transactions which are guaranteed to either completely occur, or have no effects; Atomicity (programming), an operation appears to occur at a single instant between its invocation and its response; Atomicity, a property of an S-expression, in a symbolic language like Lisp
The book depicts the failure detector as a tool to improve consensus (the achievement of reliability) and atomic broadcast (the same sequence of messages) in the distributed system. In other words, failure detectors seek errors in the process, and the system will maintain a level of reliability. In practice, after failure detectors spot crashes ...
