ACID

(programming)
A mnemonic for the properties a transaction should have to satisfy the Object Management Group Transaction Service specifications. A transaction should be Atomic, its result should be Consistent, Isolated (independent of other transactions) and Durable (its effect should be permanent).

The Transaction Service specifications which part of the Object Services, an adjunct to the CORBA specifications.

ACID

(Atomic, Consistent, Isolated, Durable) The properties of a transaction in a well-designed database management system (DBMS). The transaction must be ATOMIC (all updating tasks must be completed or nothing is done), CONSISTENT (it cannot leave the database in a state that violates any integrity rules), ISOLATED (remain invisible to other operations until completed) and DURABLE (will complete or be reversed if the system fails in the interim).
