A schema builder lets the user add custom fields, objects, and relationships to the schema. Unlike other apps and programs, the schema builder allows you to search and edit custom field without clicking from page to page. You can easily edit or add a new custom object while viewing the details of your schema.
You can easily look up the master-detail relationships when you are on the schema builder without browsing from page to page of the schema. Not only you can edit the fields but also allow you to save the changes you have made. This saves a lot of time and effort thus making you complete the work quickly.
