Summary  
This chapter explains how to organize data resources hierarchically into projects, datasets, and tables, configure metadata such as location and expiration, upload data, and manage access permissions.

General domain of usage  
Cloud data warehousing

In **BigQuery**, data is organized using a clear three-level structure: **projects**, **datasets**, and **tables**. This hierarchy helps manage access, billing, and data organization in a consistent way.

**Projects** act as top-level containers. They control billing, permissions, and access to all BigQuery resources. Every dataset and table belongs to a specific project.

**Datasets** group related tables together and define important properties such as data location. Choosing the correct location is critical for performance optimization and regulatory compliance.

**Tables** store the actual data and support efficient querying at scale. BigQuery makes it easy to upload data from various sources and formats. To support automated data lifecycle management, tables can be configured with **expiration settings**, helping reduce storage costs by removing outdated data automatically.
