# Data storage

This page is the technical reference for data storage on Nuvolos: activating tables in a Space, navigating the Tables view, running queries, uploading and accessing data from inside and outside Nuvolos, and the supporting tools (ODBC drivers, DBeaver, big-data exports).

Tabular data on Nuvolos is stored in the Scientific Data Warehouse (SDW), which uses Snowflake as the underlying database engine. For the conceptual model - why Nuvolos integrates a data warehouse, how dataset Spaces work, vintaging, and the two connection modes - see [Concepts › Data storage](/concepts/data-integration.md).

## Start working with data

Nuvolos differentiates two types of data:

1. Tabular data stored in some database management system
2. Data stored in regular files

This page describes working with *tabular data.* For working with files, consult [our guide](/reference/file-system-and-storage.md) to the file system.

{% hint style="info" %}
This documentation distinguishes tabular and file based data.

Tabular data refers to data stored in the Scientific Data Warehouse (SDW), a SQL compliant cloud-based data warehouse.

File based data means data that is stored on a regular file system. This guide focuses on database-stored datasets.
