# Table Constraint
|
||
|
||
In OpenMetadata, **table constraint** are integral to understanding the relationships between tables, enhancing data discovery, and facilitating comprehensive data lineage tracking. By default, the ingestion process captures these constraints, allowing users to visualize and manage table relationships effectively.
|
||
|
||
## Viewing table constraint
|
||
|
||
Once the metadata ingestion is complete, foreign key relationships can be explored within the OpenMetadata UI:
|
||
|
||
### Navigate to the Table Details Page:
|
||
- Access the desired table within the OpenMetadata interface.
|
||

|
||
|
||
### Explore Table Constraints:
|
||
