- [Data domains](https://docs.atlan.com/llms/governance/domains/manage-data-domains/llms.txt) are a way to group data products together, for example by business area. Data domains themselves can be organized in a hierarchical structure of subdomains.
- [Data products](https://docs.atlan.com/llms/governance/domains/manage-data-products/llms.txt) are a way to group assets together. They both define the assets included in the product, as well as the assets that can be used to consume the product (as output ports).
