  *Figure 2-1 Architectural view of Content Manager OnDemand*
  
  Data is loaded and retrieved from the Content Manager OnDemand server through a network 
  connection (TCP/IP). The advantages of this design are listed: 
  
  (cid:2) The instance components can be physically distributed across the network. 
  
  (cid:2) System users (client systems) can be anywhere on the network. By using the Internet, the 
  clients can be anywhere in the world. 
  
  (cid:2) The “load process” can run either on the library server, the object server, or on any other 
  system (containing the appropriate software) that is attached by network to both the library 
  and object server. 
  
  (cid:2) This design also allows the library server and object servers to be placed on the same 
  system (or logical partition (LPAR)) or on two (or more) systems (LPARs).
