ACID Quiz

What is transaction processing?

• A type of database management system

• A process where transactions are divided into individual operations called transactions

• A programming language for creating databases

• A method for encrypting data

What does CRUD stand for?

• Create, Read, Update, Delete

• Connect, Retrieve, Use, Disconnect

• Create, Retrieve, Utilize, Delete

• Connect, Read, Update, Disconnect

What does ACID stand for in database transactions?

• Authentication, Consistency, Isolation, Durability

• Authentication, Confidentiality, Integrity, Durability

• Atomicity, Consistency, Isolation, Durability

• Atomicity, Consistency, Integrity, Durability

What does atomicity ensure in a database transaction?

• Data is encrypted for security

• A change to a database is either completely performed or not at all

• A database remains in a consistent state after a transaction

• Transactions are processed in parallel

What is an example of consistency in a database?

• Transferring funds from one bank account to another

• Locking a record during a transaction

• Splitting a transaction into smaller parts

• Saving changes to permanent storage

How is isolation achieved in a database management system?

• By performing all transactions at the end of the day

• By saving changes to temporary storage

• By implementing a system of record locking

• By encrypting the data

What does durability ensure in a database transaction?

• Changes are immediately written back to permanent storage

• Changes are saved to temporary storage

• Data is only accessible to authorized users

• Transactions are reversible

What role does 'Isolation' play in database transactions?

• Ensures that transactions are securely encrypted

• Guarantees that transactions are reversible

• Makes sure transactions are executed with minimal locking

• Prevents transactions from affecting each other until they're completed

Why is 'Atomicity' important in database transactions?

• It ensures that all operations within a transaction are completed successfully before committing

• It allows transactions to be divided into smaller, more manageable operations

• It ensures data is only accessible to authorized users

• It guarantees that transactions can be executed in parallel
