What does the term 'ACID' stand for in database transactions?
Correct Answer: Atomicity, Consistency, Isolation, Durability
  • Step 1: Understand that ACID is an acronym used in databases.
  • Step 2: Break down the acronym ACID into its four parts: Atomicity, Consistency, Isolation, and Durability.
  • Step 3: Learn what each part means:
  • - Atomicity: This means that a transaction is all or nothing. It either completes fully or not at all.
  • - Consistency: This ensures that a transaction brings the database from one valid state to another valid state.
  • - Isolation: This means that transactions occur independently without interference from each other.
  • - Durability: This guarantees that once a transaction is committed, it will remain so, even in the event of a system failure.
  • Step 4: Remember that these properties help ensure that database transactions are processed reliably.
  • Atomicity – Ensures that all operations in a transaction are completed successfully or none at all.
  • Consistency – Guarantees that a transaction will bring the database from one valid state to another, maintaining all predefined rules.
  • Isolation – Ensures that transactions are executed in isolation from one another, preventing concurrent transactions from affecting each other.
  • Durability – Ensures that once a transaction has been committed, it will remain so, even in the event of a system failure.
