# About Sources

> Sources connect Validio to your data systems. A source represents a single table, topic, or dataset from a data warehouse, data stream, query engine, or other supported system.

Sources connect Validio to your data systems, including data warehouses, data streams, query engines, and more. A source defines the specific dataset or table that you want to monitor and validate. Validio can validate both structured and semi-structured data.

To view your sources and source details, see [Reviewing Sources](https://docs.validio.io/v11.1/docs/sources/source-details.md). To add or manage sources, see [Managing Sources](https://docs.validio.io/v11.1/docs/sources/managing-sources.md).

## Configuring a source

To add and configure a source, you need to:

1. **Add a credential** to give Validio access to your data system. For more information, see [About Credentials](https://docs.validio.io/v11.1/docs/credentials.md).
2. **Specify the dataset** (table, topic, or custom SQL query) that you want to monitor.
3. **Define a polling schedule** for how often Validio reads data from the source. For data streams, data is read as soon as it is available.
4. **Assign a priority** (None, Low, Medium, High, or Critical) to indicate the importance of issues detected on the source.

Creating and updating sources requires `sources:WRITE` permissions. For more information, see [About Validio RBAC](https://docs.validio.io/v11.1/docs/access-and-settings/about-validio-rbac.md). For step-by-step instructions, see [Add a New Source](https://docs.validio.io/v11.1/docs/sources/managing-sources.md#add-a-new-source). If you already have credentials configured, you can also convert discovered assets into sources from the [Catalog](https://docs.validio.io/v11.1/docs/catalog.md) or [Lineage](https://docs.validio.io/v11.1/docs/lineage.md) pages.

## Schema detection and inference

Validio reads the schema from metadata in the source for most unstructured data types and infers the schema from existing data for most semi-structured and complex data types. Schema checks run hourly, and detected schema changes are reported as [source errors](https://docs.validio.io/v11.1/docs/incidents-and-errors/errors.md), not incidents.

For more information and the full list of supported data types per source, see [Schema Detection](https://docs.validio.io/v11.1/docs/schema-and-profiling/schema-detection.md).
