[from Gk. atomos, indivisible]

1. Indivisible; cannot be split up. For example, an instruction may be said to do several things ‘atomically’, i.e., all the things are done immediately, and there is no chance of the instruction being half-completed or of another being interspersed. Used esp. to convey that an operation cannot be screwed up by interrupts. “This routine locks the file and increments the file's semaphore atomically.

2. [primarily techspeak] Guaranteed to complete successfully or not at all, usu. refers to database transactions. If an error prevents a partially-performed transaction from proceeding to completion, it must be “backed out”, as the database must not be left in an inconsistent state.

Computer usage, in either of the above senses, has none of the connotations that ‘atomic’ has in mainstream English (i.e. of particles of matter, nuclear explosions etc.).

In the mathematical field of order theory, given two elements a and b of a partially ordered set, one says that b covers a, and writes a <: b or b :> a, if a < b and there is no element c such that a < c < b. In other words, b covers a if b is greater than a and minimal with this property, or equivalently if a is smaller than b and maximal with this property.

In a partially ordered set with least element 0, an atom is an element that covers 0, i.e. an element that is minimal among the non-zero elements. A partially ordered set with a least element is called atomic if every non-zero element b > 0 has an atom a below it, i.e. b ≥ a :> 0.

A partially ordered set is called relatively atomic (or strongly atomic) if for all a < b there is an element c such that a <: c ≤ b or, equivalently, if every interval [a, b] is atomic. Every relatively atomic partially ordered set with a least element is atomic.

A partially ordered set with least element 0 is called atomistic if every element is the least upper bound of a set of atoms. Every finite poset is relatively atomic, and every finite poset with 0 is atomic. But the linear order with three elements is not atomistic.

Atoms in partially ordered sets are abstract generalizations of singletons in set theory. Atomicity (the property of being atomic) provides an abstract generalization in the context of order theory of the ability to select an element from a non-empty set.

The terms coatom, coatomic, and coatomistic are defined dually; thus in a partially ordered set with greatest element 1:

  • A coatom is an element covered by 1
  • The set is called coatomic if every b < 1 has a coatom c above it
  • The set is called coatomistic if every element is the greatest lower bound of a set of coatoms.
