# Change management

If you need to change a table or a dashboard, Select Star has a few ways to help do this as smoothly as possible.

* Use [Lineage](#lineage) to find upstream and downstream dependencies for the dataset you intend to change.
* See [related dashboards & tables](#related-dashboards-and-tables) for to identify other dependencies.
* [Discuss changes with owners and creators](#discuss-changes-with-owners-and-creators) before making a change.

## Lineage

[Data Lineage](/features/lineage.md) is designed to indicate where the data is coming from, so you can find dependencies of each table, column, or dashboard. Click on the **Lineage** tab/button from a table view to see how it connects to your other tables and dashboards.

{% hint style="info" %}
Make sure **Dashboards** is checked ☑️ at the bottom of the lineage graph if you want to see dashboards or reports.
{% endhint %}

You can use the lineage graph and the left sidebar to see upstream and downstream dependencies for the table you are planning to change.

## Related dashboards & tables

The **Related** tab on a database table shows other relevant data objects, such as other tables or dashboards.

**Downstream Dashboards** shows any dashboards using data from the table you're currently looking at.

**Related Tables**, similar to joins, are tables that are frequently used together in `SELECT` queries.

**Similar Tables** will show tables that have exactly the same fields and column types as the table you’re viewing. This can be used to identify duplicate tables that may need to be removed.

## Discuss changes with owners and creators

If you need more information about how the data is being used, or want to notify anyone of the potential change, you can post a comment in the [Discussion](/features/discussion.md) section. Table Owners will be notified automatically, and anyone who checks the table will be aware of any upcoming changes.
