text: The skill level of the users might be a determining factor in the degree of authority that is 
  granted. It takes a more skilled user to define indexes and report parameters than to set up 
  users and groups. A decentralized system is typically used when data from different sources 
  is stored on the same Content Manager OnDemand system but must be maintained 
  independently of other data. Decentralization also makes sense when report loading and 
  processing needs are limited to a specific group of users for security purposes or when 
  administrators that add users and groups must be prevented from accessing report data. 
  
  The decision about whether to use a centralized or a decentralized administration model is 
  best made*before*any data is set up in the system. Even though the type of administration that 
  is chosen can be changed later, the amount of work that is involved in that change is greater 
  than the amount of work that is necessary to study the requirements of the system and 
  implement the appropriate administration policies from the beginning. 
  
  In this section, we describe different types of users, followed by a description of a 
  decentralized administrative plan. We also introduce a new administrative tool, Content 
  Manager OnDemand XML Batch Administration, which is a command-line program that is run 
  on the Content Manager OnDemand server.
