There is a concept in Salesforce called custom objects which provide structure for organizing and viewing data, similar to how an iPhone's settings can be customized to fit individual preferences. Custom objects are containers that can be created to handle specific needs of an organization or industry, providing flexibility and customization options. They can be used when tracking unique data that doesn't fit into standard Salesforce objects, such as invoices or addresses, and can be associated with any record in the system. Creating a custom object involves navigating through the Object Manager tab in Setup, entering a label and name, selecting a style for the tab, and launching the New Custom Tab Wizard to add it to the system. With custom objects, organizations can build Salesforce to fit their unique needs, providing a tailored solution for managing data and workflows.
