text: **17.3 Content Federation Services for Content Manager**
  **OnDemand architecture**
  
  Content Federation Services is based on the federation implementation strategy for 
  managing distributed content. The distinguishing feature of this strategy is the global catalog. 
  The global catalog is a searchable database that contains information about content that is 
  stored in various repositories and repository types in separate locations throughout the 
  enterprise that are identified for federation. Enabling Content Federation Services for Content 
  Manager OnDemand does not change the architectural design of Content Manager 
  OnDemand. Content Federation Services for Content Manager OnDemand is a mid-tier 
  process that enhances your ability to manage content more efficiently.

  Manager OnDemand, Content Navigator, and Content Manager OnDemand clients.
