In computer science, ACID (''Atomicity, Consistency, Isolation, Durability'') is a set of properties that guarantee that database transactions are processed reliably. In the context of databases, a single logical operation on the data is called a transaction. For example, a transfer of funds from one bank account to another, even involving multiple changes such as debiting one account and crediting another, is a single transaction. Jim Gray defined these properties of a reliable transaction system in the late 1970s and developed technologies to achieve them automatically.〔Gray, Jim & Andreas Reuter. ''Distributed Transaction Processing: Concepts and Techniques''. Morgan Kaufmann, 1993; ISBN 1-55860-190-2.〕 In 1983, Andreas Reuter and Theo Härder coined the acronym ''ACID'' to describe them.〔 These four properties, atomicity, consistency, isolation, and durability (ACID), describe the major highlights of the transaction paradigm, which has influenced many aspects of development in database systems. 〕 ==Characteristics== The characteristics of these four properties as defined by Reuter and Härder: 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「ACID」の詳細全文を読む スポンサード リンク
