# Connections

The CARTO Workspace includes functionalities for registering and managing connections to your data warehouse(s) of choice. Once you have created a connection, you will then be able to perform different operations with the available data, like performing advanced spatial analysis with CARTO’s Analytics Toolbox or creating stunning maps in Builder.

Currently we support connectivity to the following data warehouses: **Google BigQuery, Snowflake, Databricks, Oracle, Amazon Redshift** and **PostgreSQL**.

**When I connect to a data warehouse, do you copy or store any data?**

No, your connection allow us to perform queries against your data on your behalf, and the results are either stored again in your data warehouse or rendered in the client, as visible maps. CARTO being fully cloud native means no storage needs, less security concerns and no need for data replication or complex ETL processing.
{% endhint %}

In the Connections section of the Workspace, you can access the list of your current connections. If you haven’t registered a connection yet, you will see the following page:

## Creating and managing connections

The first step when creating a connection is to select a data warehouse. The required setup for each data warehouse is slightly different so we have prepared a guide for each of the available providers:

* [Google BigQuery](https://docs.carto.com/carto-user-manual/connections/bigquery)
* [Snowflake](https://docs.carto.com/carto-user-manual/connections/snowflake)
* [Databricks](https://docs.carto.com/carto-user-manual/connections/databricks)
* [Oracle](https://docs.carto.com/carto-user-manual/connections/oracle)
* [Amazon Redshift](https://docs.carto.com/carto-user-manual/connections/redshift)
* [PostgreSQL](https://docs.carto.com/carto-user-manual/connections/postgresql)

After you've created your connection, you can edit or delete it any time, or share it with users and groups in your organization:

* Deleting a connection [guide](https://docs.carto.com/carto-user-manual/connections/deleting-a-connection)
