Atomicity

Atomicity (database systems) is a property of database transactions which are guaranteed to either completely occur, or have no effects.

In chemistry, atomicity is a synonym for valence.

Atomicity may also refer to:

* Linearizability, in computer science, especially parallel algorithms, 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, to describe whether an expression is made of atoms (numbers or symbols) or is a list of S-expressions

* Atomicity, an element of orthogonality in a component-based system

* Atomicity in order theory. See Atomic (order theory).
