To create a custom object along with multiple fields and relationships efficiently from a single interface, the Schema Builder is the ideal tool:
* A. Schema Builder. This graphical tool provides a drag-and-drop interface for creating and modifying objects and fields in Salesforce, allowing for a visual layout of database schema.
Steps to use Schema Builder:
* Go to Setup # Schema Builder.
* Drag the 'Object' element into the schema area to create a new custom object.
* Define the object's properties (e.g., label, API name).
* Drag field elements like Text, Number, or Lookup into the object to create fields.
* Configure each field's properties according to your requirements.
* Connect objects via lookup or master-detail relationships by dragging the relationship fields between them.
* Save the layout to create all elements in Salesforce.
