Schema Builder is a tool that lets you visualize your data model in a useful way and edit it. It is primarily useful for understanding and designing complex data models and their relationships between various objects.
The Schema Builder helps you visualize the objects, fields, and the relationship between them. It has a drag-and drop interface for the objects, allowing you to easily add a custom object or a new field. It can also save the schema layout when moving an object. Furthermore, it provides a pictorial representation of objects, fields, and relationships.
