text: **3.2.2 System administration**
  
  Content Manager OnDemand can centralize or decentralize the administration of the system. 
  A centralized environment means that one type of user, a system administrator, controls the 
  creation and access to all of the objects that are defined on the system. A decentralized 
  environment means that the tasks of the system administrator are divided and assigned to 
  other users. The responsibilities of the other users might vary from user administration, group 
  administration, application group administration, folder administration, or any combination of 
  the administrative tasks. 
  
  You need to decide whether to centralize or decentralize the administration of the system 
  before objects are added to the system. Although the decision is reversible, the amount of 
  work that is required to change from one type of administration to the other can be significant 
  if many users, groups, folders, and application groups are already defined to the Content 
  Manager OnDemand system. 
  
  Many ways exist to decentralize the administration of the system because of the various user 
  types and the additional authority levels that can be specified for users. Two specific models 
  are described in this section: the object type model and the object owner model. 
  
  **Object type model**
  In the object type model, which is shown in Figure 3-23, all of the objects on the system are 
  logically grouped into administrative domains according to the type of the object. The 
  administrator of a domain maintains all of the objects within the domain. For example, an 
  application group, folder, or cabinet administrator maintains all of the application, application 
  group, folder, and cabinet objects on the system.
