# Schema Reference

The application schema is used to configure the objects returned from a connector.

> [!NOTE]
>
> - The **Account Schema** tab is used to define the attributes for each object type in the application being configured. The schema attributes can be defined as **Entitlement** or **Multi-Valued**. Refer to [Managing Source Account Schemas](<https://documentation.sailpoint.com/saas/help/accounts/schema.html>) for more information.
> - The schema attributes that are not present by [default](<#default-account-schema>) must be defined as strings if not specified.

The MongoDB Cloud - Atlas connector uses the following default correlation and object configurations.

## Default Account Schema

Each source supports a variety of details, or attributes, about each user who has an account, such as their name, email address, manager name, and location.

The set of account attributes each source stores and how they're organized is known as the account's *schema*. To best represent your data, you can configure sources to use an account schema matching the one you use in the external connector. Refer to [Managing Source Account Schemas](<https://documentation.sailpoint.com/saas/help/accounts/schema.html>) for more information.

### Default Account ID

SailPoint requires that certain attributes remain in your configuration. These attributes are referred to as *account IDs*.

> [!CAUTION]
>
> Changing the attribute marked as the account ID after aggregating accounts can result in duplicate accounts being created. To avoid this, either reset the accounts on this source before editing the account ID attribute or edit the account ID attribute before aggregating accounts.
>
> To resolve issues caused by changing account IDs, reconfigure them to their default values.

The following table lists the default account IDs for this connector:

| Account ID | Schema Object Type |
| --- | --- |
| Id | Account |
| Native Identity | Role |

### Default Account Attributes
