# ACID Compliance

> **Definition:** ACID compliance is a set of database transaction properties (Atomicity, Consistency, Isolation, Durability) that guarantee database transactions are processed reliably, maintaining data integrity even in the event of crashes or power outages.

## In depth

In high-throughput databases, ACID properties ensure that complex transaction blocks are executed as a single unit. If any part of the transaction fails, the entire transaction is rolled back (Atomicity). Transactions must leave the database in a valid state (Consistency). Concurrent transactions must execute without interfering with one another (Isolation). Once committed, transactions remain persisted in the database (Durability). This is critical for billing ledgers and inventory controls.

## How ERPStack applies this

We enforce strict ACID compliance using PostgreSQL transactions wrapped in Drizzle ORM database sessions. This guarantees that balance ledgers and inventory counts never logically drift.
