# Segment Membership Data Model Object

Each time you publish a segment, a data model object (DMO) is created or updated to store segment membership information. To identify who's included in a segment, use the Segment Membership DMO (type Segment\_Membership). If there are no dependencies on the DMO, you can delete segment membership DMOs manually.

Each object that you build a segment on has a set of membership DMOs across all segments using it. The latest segment membership shows the profile IDs included in the latest segment publish. The history segment membership shows the profile IDs included in the previous segment publish from the last 30 days. When a publish starts and a segment member no longer satisfies the segment criteria, the member is removed from the segment membership table.

You can interact with segment membership data in three ways.

- To verify the segmentation results, view the data in Data Explorer.
- To find insights in a business dashboard, interact with the data in Tableau.
- Query the segment membership DMO using SOQL, Query APIs, or the segmentation REST API.

- **[Segment Membership DMO Schema](https://help.salesforce.com/s/articleView?id=data.c360_a_segment_membership_dmo_schema.htm&release=264.0.0&type=5)**  
    The segment membership DMO has these object-level and field-level schema attributes. These fields are available in the latest and history segment membership DMOs.
- **[View Segment Members in Data Explorer](https://help.salesforce.com/s/articleView?id=data.c360_a_membership_data_data_explorer.htm&release=264.0.0&type=5)**  
    After publishing your segment in Data 360, you can validate the segment membership in Data Explorer.
- **[Query Data in Data Model using Tableau](https://help.salesforce.com/s/articleView?id=data.c360_a_membership_data_data_model.htm&release=264.0.0&type=5)**  
    Download your segment membership data in Data 360 and then analyze in Tableau.
- **[Query Data using SOQL](https://help.salesforce.com/s/articleView?id=data.c360_a_membership_data_soql.htm&release=264.0.0&type=5)**  
    In Data 360, you can analyze segment membership data using SOQL in Data Explorer.
