Schema Builder provides a dynamic environment for viewing and modifying all the objects and relationships in your app. This greatly simplifies the task of designing, implementing, and modifying your data model, or schema.
You can view your existing schema and interactively add new custom objects, custom fields, and relationships, simply by dragging and dropping. Schema Builder automatically implements the changes and saves the layout of your schema any time you move an object. This eliminates the need to click from page to page to find the details of a relationship or to add a new custom field to an object in your schema.
Schema Builder provides details like the field values, required fields, and how objects are related by displaying lookup and master-detail relationships. You can view the fields and relationships for both standard and custom objects.
From Setup, enter Schema Builder in the Quick Find box, then select Schema Builder.
When working with Schema Builder:
Salesforce populates Field Name using the field label. This name can contain only underscores and alphanumeric characters, and must be unique in your org. It must begin with a letter, not include spaces, not end with an underscore, and not contain two consecutive underscores.
Any field you add through Schema Builder isn’t automatically added to the page layout. You will need to edit the page layout to specify where the field should be displayed.
By default, the field level security for custom fields is set to visible and editable for internal profiles. Fields that are not normally editable, such as formulas and roll-up summary fields, are visible and read-only. To manage permissions of a custom field, click the element name or label and select Manage Field Permissions.
