The phrase "all or nothing" succinctly describes the first ACID property of atomicity. When an update occurs to a database, either all or none of the update becomes available to anyone beyond the user or application performing the update. This update to the database is called a transaction ...

Definition Theatomicity of actionson a database is a fundamental guarantee that database systems provide to application programs. Whatever state modifications an atomic action may perform are guaranteed to be executed in anall-or-nothingmanner: either all state changes caused by the action will be ...

Atomicity is a property that ensures that a database follows the all or nothing rule. In other words, the database considers all transaction operations as one whole unit or atom. Thus, when a database processes a transaction, it is either fully completed or not executed at all. If a sing...
1 Introduction The absence or misspecification of the scope of atomic blocks in a concurrent program may trigger atomicity violations and lead to runtime misbehaviors. Low-level dataraces occur when the program includes unsynchronized ac- cesses to a shared variable, and at least one of those ...
1 Introduction In shared memory concurrent software, to prevent erroneous behaviour due to unanticipated thread interactions, programmers ensure that appropriate blocks of code are atomic [18]. Atomicity is a stronger property than race-freedom [6], guaranteeing against high-level concurrency bugs such...
However, a scientific workflow typically consists of computational and analytical steps that are more complex than database operations. On the other hand, although several provenance models [22], [37], [6], [12], [3] have been proposed for scientific workflows, none of them supports the ...
