A transaction is an agreement, communication, or movement carried out between separate entities or objects.

ACID Transactions: Tech Library: Products: NuSphere (337 words)
Transactions always operate on a consistent view of the data and when they end always leave the data in a consistent state.
The effects of concurrently running transactions are invisible to this transaction, and the effects of this transaction are invisible to others until the transaction is committed.
Until the transaction commits, not only are any changes made by that transaction not durable, but are guaranteed not to persist in the face of a system failure, as crash recovery will rollback their effects.
Database transaction - Wikipedia, the free encyclopedia (364 words)
A database transaction is a unit of interaction with a database management system or similar system that is treated in a coherent and reliable way independent of other transactions that must be either entirely completed or aborted.
In database products the ability to handle transactions allows the user to ensure that integrity of a database is maintained.
When this happens it is usually important to be sure that the database is not left with only some of the queries carried out.
