Atomicity (database systems)

Atomicity in the context of concurrency control
Atomicity - either all or no operations are completed. See concurrent programming
Atomicity in the Component Based Paradigm context
Atomicity is an element of orthogonality guaranteeing hermetic interfaces among components of a component-based system. This avoids that malfunctions in one component would result into side-effects in another. In addition it guarantees that services provided by a component are either offered as a whole, or not at all. Systems build according to this design principle localise the side-effects of changes within the module that such change was manifested. Changes affect the emergent behaviour of such a system only if their technical effect is explicitly described by the formal definition of its logic.
