ACID Model

Search this site with Google

A set of properties of database transactions that guarantee reliable processing. This topic is more relivent to the implementaion and not usually a concern of the Information Architect.

The ACID model focuses on the Atomicity, Consistency, Isolation and Durability of logical transactions. Some logical transactions, such as transferring funds from one account to another, may involve multiple operations, such as debiting one account and crediting another. The ACID model tests that these complex transactions can be treated as a single activity and that any interruption will not leave the database in an unexpected state.

This can be thought of as a database version of a Race Condition.
