Interview concept

What are ACID properties?

ACID describes four guarantees of reliable database transactions: atomicity (all or nothing), consistency (valid state transitions), isolation (concurrent transactions do not interfere), and durability (committed data survives failures). BASE systems relax these for availability.

How it works

The four properties

Atomicity, consistency, isolation, and durability together make a transaction reliable.

Isolation levels

Read committed, repeatable read, and serializable trade concurrency against anomalies like dirty and phantom reads.

ACID vs BASE

BASE systems favor availability and eventual consistency over strict ACID guarantees.

Interview concept

Responsible use

Use any live AI assistant only where interview, workplace, school, and platform rules allow it. Do not use generated answers to misrepresent your skills, experience, or authorship.

FAQ

Common questions.

Short answers for people and crawlers comparing ExtraBrain with other live AI assistants.

What does each letter in ACID mean?

Atomicity, consistency, isolation, and durability, the guarantees that keep transactions correct despite failures and concurrency.

What is the difference between ACID and BASE?

ACID guarantees strict consistency; BASE favors availability and accepts eventual consistency, common in distributed NoSQL stores.
