The different objects within the Sales Cloud serve specific purposes that help users track and manage their sales data. For example, the Accounts object represents a company or individual that users are selling to, while the Contacts object represents those associated with those Accounts. The Opportunities object represents the potential sales that users are working on and tracks the progress of those sales. The Sales Cloud also includes several other objects that help users manage their sales data, such as the Leads object, which represents potential customers that users are trying to sell to.
