ACID
PronunciationA-SID
Definition
ACID is a set of properties (Atomicity, Consistency, Isolation, Durability) that guarantee database transactions are processed reliably. It ensures that even in the event of errors or power failures, data remains accurate and consistent.
Where you hear it
During database architecture discussions, when choosing a database engine, or when designing systems that require high data integrity.
Examples
We chose a relational database because our financial records require ACID compliance.
The system ensures ACID properties to prevent partial data updates during a transaction.
Common mistake
Thinking that all databases are ACID-compliant by default; many NoSQL databases prioritize performance or availability over strict ACID guarantees.
