Master Hibernate and JPA with Spring Boot in 100 Steps - Step 59 - Transaction Management - ACID Properties

This video provides an overview of ACID properties in transaction management, explaining each component: Atomicity ensures transactions are fully completed or not at all; Consistency maintains system state integrity; Isolation manages transaction visibility; and Durability ensures data persistence post-transaction. Each property is crucial for reliable transaction management.

What does the 'A' in ACID properties stand for?

• Adaptability

• Availability

• Atomicity

• Accessibility

Which of the following best describes Atomicity in transaction management?

• A transaction can be partially successful.

• A transaction must be either fully completed or not executed at all.

• A transaction can be reversed at any time.

• A transaction is always visible to other transactions.

In the context of transaction management, what does Concurrency refer to?

• The ability to ensure data durability.

• The ability to execute a transaction in isolation.

• The ability to execute multiple transactions simultaneously.

• The ability to maintain data consistency.

What is a key aspect of Consistency in transactions?

• Ensuring the system remains in a consistent state after a transaction.

• Ensuring transactions are isolated from each other.

• Ensuring transactions are durable.

• Ensuring transactions are atomic.

In a bank transfer example, what indicates a consistent state?

• The transaction is completed quickly.

• The transaction is visible to other transactions.

• The total balance remains unchanged regardless of transaction success.

• The transaction can be reversed.

What does Isolation in ACID properties determine?

• How transactions are initiated.

• How transactions are executed in parallel.

• How transactions are stored permanently.

• How changes in one transaction are visible to others.

What is the main goal of Durability in transaction management?

• To ensure transactions are executed quickly.

• To ensure transactions are isolated.

• To ensure transactions can be reversed.

• To ensure transaction results are permanent even after failures.
