# Analytics Toolbox Overview

The CARTO Analytics Toolbox is a suite of functions and procedures to easily enhance the geospatial capabilities available in the different leading cloud data warehouses.

It is currently available for Google BigQuery, Snowflake, Redshift, Databricks and PostgreSQL. Oracle connections are supported for workflows and visualization, but the Analytics Toolbox is not yet available for Oracle.

The Analytics Toolbox contains more than 100 advanced spatial functions, grouped in different modules.

## How does it work <a href="#how-does-it-work" id="how-does-it-work"></a>

Technically speaking, the CARTO Analytics Toolbox is a set of SQL UDFs and Stored Procedures that run natively within each data warehouse, leveraging their computational power and scalability and avoiding the need for time consuming ETL processes.

The functions can be executed directly from the CARTO Workspace or in your cloud data warehouse console and APIs, using SQL commands.

Here’s an example of a query that returns the compact H3 cells for a given region, using Analytics Toolbox functions such as `H3_POLYFILL()` or `H3_COMPACT()` from our H3 module.

Check the documentation for each data warehouse (listed below) for a complete SQL reference, guides, and examples.

```sql
WITH q AS (
  SELECT `carto-un`.carto.H3_COMPACT(
  `carto-un`.carto.H3_POLYFILL(geom,11)) as h3
  FROM `carto-do-public-data.carto.geography_usa_censustract_2019`
  WHERE geoid='36061009900'
) 

SELECT h3 FROM q, UNNEST(h3) as h3
```

{% hint style="info" %}
Some Analytics Toolbox modules (e.g., Location Data Services) require an **AT Gateway** to connect your data warehouse to CARTO's APIs. The gateway deployment differs depending on whether you use CARTO SaaS or Self-Hosted. See [Analytics Toolbox Gateway](https://docs.carto.com/data-and-analysis/analytics-toolbox-gateway) for details.
