Database vocabulary: ACID

database glossary tech

Databases are often described in terms of their ACID properties (e.g. "eventual consistency"), so knowing the vocabulary is useful when considering a database solution. Some contemporary database management systems intentionally disregard ACID properties in a tradeoff for other gains.

ACID is an acronym representing four traits of a database transaction that will guarantee valid data even if the transaction is not completed. Transactions that violate these principles will leave the database in an unknown or invalid state.

The influential paper describing these properties is "Principles of Transaction-Oriented Database Recovery" by Haerder and Reuter, 1983.
