The Object Manager is where field dependencies for an object can be reviewed. The Object Manager allows the user to view and manage the metadata of standard and custom objects in Salesforce, such as fields, page layouts, record types, buttons, and actions. Field dependencies are a type of metadata that define the relationship between a controlling field and a dependent field. For example, a field dependency could be set up so that the values available in a picklist field called Region depend on the value selected in another picklist field called Country. Profiles are used to define the baseline access and permissions for users based on their license type and job function. App Builder is a tool that allows the user to create and customize apps and pages in Salesforce using drag-and-drop components.
