  *Figure 3-1 Content Manager OnDemand system components relationship*
  
  To help you better understand how to perform report administration, we use the example 
  company that is mentioned in 1.2.1, “Background information of an example company” on 
  page 6 with the Content Manager OnDemand Administrator Client running on Windows to 
  create the required system components. We use the monthly credit card statements that are 
  generated by AFinancial Co in our example. These statements are stored in a single 
  application group in Content Manager OnDemand. 
  
  **3.1.1 Storage sets**
  
  When you define a report, the first component to create is a storage set if one does not exist. 
  A*storage set*is a named collection of primary storage nodes that support application groups 
  with similar archive storage management requirements.
