Return to ACID (Atomicity, Consistency, Isolation, Durability)
In database systems, atomicity is one of the ACID (Atomicity, Consistency (database systems) | Consistency, Isolation (database systems) | Isolation, Durability (database systems) | Durability) database transaction | transaction properties. An atomic transaction is an indivisible and Irreducibility | irreducible series of database operations such that either all occur, or nothing occurs.
In philosophy, systems theory, science, and art, emergence occurs when a complex entity has properties or behaviors that its parts do not have on their own, and emerge only when they interact in a wider whole.
Emergence plays a central role in theories of integrative levels and of complex systems. For instance, the phenomenon of life as studied in biology is an emergent property of chemistry and physics.
