To advertise on TV, radio, print, and social under one banner called New Runners and aggregate total statistics for this marketing effort, an administrator should use Parent campaign field on Campaign object. This field allows creating hierarchical relationships between campaigns by specifying one campaign as parent of another campaign. Parent campaigns roll up statistics from child campaigns such as number of leads generated, amount of revenue won etc. For example, an administrator can create four child campaigns for TV, radio, print and social ads respectively and link them to one parent campaign called New Runners using Parent campaign field. Junction object, lookup relationship, and master-detail relationship are not features related to Campaign object or hierarchy.
