SQL Database Concepts Interview Question:

Explain ACID?

Submitted by: Administrator

- ACID (Atomicity Consistency Isolation Durability) is a quality sought after in a reliable database. Here's the relevance of each quality:
- Atomicity is an all-or-none proposition.
- Consistency - it guarantees that your database is never left by a transaction in a half-finished state.
- Isolation - it keeps transactions separated from each other until they're finished.
- Durability - it ensures that the database keeps a track of pending changes in a way that the server can recover from an abnormal termination.
