# Catalog Overview

## Overview

The Catalog is your central hub for exploring and understanding your data landscape. It provides a hierarchical view of all your data sources, schemas, tables, and columns, making data discovery intuitive and efficient.

Key capabilities include:

- **Data Discovery**: Browse your metadata at any level from data source down to individual columns
- **Trust Scoring**: View trust scores and quality metrics to understand data reliability
- **Test Coverage**: Identify testing gaps and see which objects have associated tests
- **Data Profiling**: Access profile statistics and data quality insights
- **Metadata Management**: Add business context through friendly names, descriptions, and tags

## Navigating the Catalog

The Catalog is organized in a hierarchical structure that you can navigate using either the tree view on the left or by clicking through the data grid.

### Data Source Level

The main Catalog view displays all your connected data sources with summary statistics.
