Transactions and ACID properties - MySQL - Quiz

Atomicity is the ACID property that ensures that a transaction is treated as a single, indivisible unit of work. It guarantees that all the operations within the transaction are either completed successfully or rolled back if any operation fails.

Consistency is the ACID property that ensures that a transaction brings the database from one consistent state to another. It guarantees that all the data modifications within the transaction adhere to the defined rules and constraints, maintaining data integrity.

Durability is the ACID property that ensures that once a transaction is committed, its changes are permanently stored and will survive any subsequent system failures. It guarantees the persistent storage and recoverability of transactional data.

Consistency is the ACID property that ensures that a transaction's execution does not violate the defined rules and constraints of the database. It guarantees that the database remains in a valid and consistent state before and after the transaction.

Isolation is the ACID property that ensures that concurrent execution of transactions does not result in data anomalies such as dirty reads and non-repeatable reads. It provides transactional isolation, preventing interference between concurrently executing transactions.

Durability is the ACID property that ensures that once a transaction is committed, its changes become permanent and cannot be undone. It guarantees the persistence of transactional data, even in the event of system failures.

Atomicity is the ACID property that ensures that a transaction can be divided into smaller, independent units of work. It guarantees the indivisibility and all-or-nothing behavior of a transaction.

Durability is the ACID property that ensures that once a transaction is committed, its changes are protected and will persist even in the event of power outages or system crashes. It guarantees the reliability and recoverability of committed data.

Isolation is the ACID property that ensures that a transaction's changes are isolated and not visible to other transactions until it is committed. It provides a level of data separation and concurrency control.

Consistency is the ACID property that ensures that a transaction brings the database from one consistent state to another, without violating any data rules or constraints. It maintains the integrity and validity of the database throughout the transaction.
