# MDP Apply Parent-Child Relationships to Share Attributes Across Data Streams

To share dimensional values across data streams, you can create parent-child relationships.

1. Navigate to the **Import** tab.
2. Expand **Data Streams List**.
3. Create a data stream or edit one.
4. At the bottom of the Data Stream page, click **Advanced**.
5. Scroll to the **Parent Child** section.
6. From the dropdown, select a parent data stream.
7. Define how to update data.
    
    - **Update Attributes** — Update existing mapped attributes across all data streams in the parent-child data pool. The update occurs based on matching entity keys each time data is ingested.
    - **Inherit Attributes and Hierarchy** —The data stream’s mapped attributes and media buy, campaign, and site hierarchy are updated across other data streams in the parent-child data pool. The update occurs based on matching entity keys each time data is ingested.
    - **Update Attributes and Hierarchy** — Update the existing mapped attributes and media buy, campaign, and site hierarchy across all data streams in the parent-child data pool. The update occurs based on matching entity keys each time data is ingested.
