# Schema changes

> Stay up to date on schema changes in your source database.

## Notification settings

By default, every user has schema change notifications enabled. You can toggle this setting by going to [Settings > My settings](https://app.artie.com/settings?tab=user) and altering the `Receive table change notifications` setting.

## Schema changes

Our schema change job runs every weekday at 6 AM PST. We will notify you if there's any changes in your source database. We will skip the notification if there aren't any.

By default, you'll receive this via email, and you can [configure Slack or Teams notifications](/account/enabling-notifications) as well.

Changes we monitor:

1. Tables added
2. Tables removed
3. Tables changed
   * Columns added
   * Columns removed
   * Columns altered (data type, default value and not null constraint)
