## Configure Database Relationships
|
||||
|
||||
In most cases you don't need this configuration, Super Graph will discover and learn
|
||||
the relationship graph within your database automatically. It does this using `Foreign Key` relationships that you have defined in your database schema.
|
||||
|
||||
The below configs are only needed in special cases such as when you don't use foreign keys or when you want to create a relationship between two tables where a foreign key is not defined or cannot be defined.
|
||||
|
||||
For example in the sample below a relationship is defined between the `tags` column on the `posts` table with the `slug` column on the `tags` table. This cannot be defined as using foreign keys since the `tags` column is of type array `text[]` and Postgres for one does not allow foreign keys with array columns.
|
||||
|
||||
```yaml
|
||||
tables:
|
||||
- name: posts
|
||||
columns:
|
||||
- name: tags
|
||||
related_to: tags.slug
|
||||
```

||||
