In Salesforce, a role is a critical component of the sharing model that helps to define the level of visibility users have on data within the organization. Specifically, roles determine the hierarchy of data access, influencing how records are shared across different levels of the organization. When a user is assigned a specific role, they can generally view, edit, and report on records based on that role's position in the hierarchy, which is especially important for managing sensitive information and ensuring proper access controls.

The visibility defined by roles allows users in higher roles to access the records owned by users in lower roles, facilitating data sharing and collaboration while maintaining security protocols. Thus, the primary function of a role in Salesforce is to dictate data visibility, which significantly impacts how data is managed and accessed within a company.

Other aspects, such as email notifications, data backups, and individual storage capacity, are governed by different settings and configurations in Salesforce, highlighting the unique function of roles specifically in data visibility.
