The following correspondences between the source and target systems apply to linking data from one HiRDB to another HiRDB:

• Correspondence between the source HiRDB and the source Datareplicator
  Source HiRDB (single server) to source Datareplicator = 1 to 1
  Source HiRDB (parallel server) to source Datareplicator = 1 to n
  
• Correspondence between the source and target Datareplicators
  Source Datareplicator to target Datareplicator = 1 to m
  Source Datareplicator to target Datareplicator = n to 1
  
• Correspondence between the target Datareplicator and the target HiRDB
  Target Datareplicator to target HiRDB = n to 1
  

In the case of linking data from one HiRDB to another HiRDB, the software configuration depends on whether the source HiRDB is a single server or a parallel server. Figure 1-11 shows the configurations of the systems when the source HiRDB is a single server, and Figure 1-12 shows the configurations of the systems when the source HiRDB is a parallel server.
