  1. Data consistency refers to the coherence of data. It exists when certain criteria for data integrity and plausibility are met. Data consistency can bechecked by error detection procedures and parity checks. Data consistency includes the automatic updating of all data instances in a company and the reliability of the data. For example, when data is entered, it can be checked for reliability and unreliable data can be sorted out. Typical examples can be found in databases or online banking, where entries are checked for plausibility and not accepted in the event of violations.
  2. Consistency is one of the four ACID properties, Atomicity, Consistency, Isolation, Durability (ACID), that transactions must meet. This involves the integrity and plausibility of the data sets. These are kept in a consistent state until the transaction is completed and are transferred to another consistent state when the transaction takes place.
