The following correspondences between the source and target systems apply to linking data from a mainframe database (XDM/SD E2, XDM/RD E2, ADM, PDMII E2, or TMS-4V/SP) to a HiRDB.

• Correspondence between the source database and XDM/DS
  See the manual VOS3 XDM Data Linkage Facility XDM/DS Description and Definition.
  
• Correspondence between XDM/DS and Datareplicator
  XDM/DS to target Datareplicator = 1 to m
  XDM/DS to target Datareplicator = n to 1
  
• Correspondence between the target Datareplicator and target HiRDB
  Target Datareplicator to target HiRDB = n to 1
  

The following figure shows the configurations of the source and target systems for linking data from a mainframe database to a HiRDB.
