# ClickHouse Analytics Database

> **Definition:** ClickHouse is a fast, open-source columnar database management system (DBMS) designed for Online Analytical Processing (OLAP), allowing companies to query billions of rows in milliseconds.

## In depth

Standard relational databases store data in row format, which slows down queries calculating sums or averages over millions of records. ClickHouse stores data in columns, allowing queries to scan only the necessary data fields, accelerating analytics calculations.

## How ERPStack applies this

We integrate ClickHouse for processing high-volume analytics, such as global supply chain tracking dashboards or real-time cybersecurity dashboards.
