In database systems, atomicity (/ ˌ æ t ə ˈ m ɪ s ə t i /; from Ancient Greek: ἄτομος, romanized: átomos, lit. 'undividable') is one of the ACID (Atomicity, Consistency, Isolation, Durability) transaction properties. An atomic transaction is an indivisible and irreducible series of database operations such that either all occur ...

ASE has its own database that can be used for storing and retrieving atoms and associated data in a compact and convenient way. There are currently five back-ends: Simple human-readable text file with a .json extension. Self-contained, server-less, zero-configuration database. Lives in a file with a .db extension. Server based database.
