# Add a Relationship

### Add a Relationship

To add a new **Relationship** between 2 **Model Objects**, there are two possibilities:

1. [Add a Relationship in the current Relationship Modeling View](https://knowledge.bigenius-x.com/add-a-relationship-in-the-current-relationship-modeling-view?hsLang=en) (description in another article)
2. Add a Relationship from the Relationship overview (in this article): Access the [**Relationship overview**](https://knowledge.bigenius-x.com/understand-relationships-overview?hsLang=en) page for the **target Model Object** of the **Relationship**:

Click on the **Add Relationships** button:

![](https://knowledge.bigenius-x.com/hubfs/image-png-May-04-2023-08-18-07-8321-AM.png)

The **Add new Relationships** side panel window is opened with the **target Model Object** name:

![2023-05-04\_10h21\_33](https://knowledge.bigenius-x.com/hs-fs/hubfs/2023-05-04_10h21_33.png?width=688&height=272&name=2023-05-04_10h21_33.png)

The **Model Object** list we can use for a **Relationship** to a **target Model Object** depends on the **Generator Configuration**.

Here, we can add a **Relationship** from a **Model Object** of type ***Hub*** to a **Model Object** of type ***Satellite***.

Select one or several **source Model Object** for Relationship(s):

Click on the **ADD** button:

- A new **Relationship** is added from the selected **source Model Object** to the **target Model Object**:  
  ![](https://knowledge.bigenius-x.com/hubfs/image-png-May-04-2023-08-29-55-9466-AM.png)
- A **Foreign Key Term** is automatically created in the **target Model Object**
- The **Mapping** between the **Business Key**(s) of the **source Model Object** to the **Foreign Key**(s) of the **target Model Object** is automatically set. 
    - It is possible to check the Mapping by flying over the Key icon of the Business Key or Foreign Key:

- A notification confirms the correct adding:

You can now map your **Foreign Key**(s) in the [Term Mapping page](https://knowledge.bigenius-x.com/map-a-source-term-with-a-target-term?hsLang=en) by choosing the **Manage Term Mappings** option in the **Context** menu for the **target Model Object** of the **Relationship**:
