Overview of RIS dBase structure
Each RRC has its own dBase
Tables for BGP updates: ‘ryyyymmdd’
Tables  for RIB dumps: ‘lribyyyymmdd
These have foreign keys pointing to ‘Prefix’,
‘Aspath’ & ‘Peer’ tables
‘Prefix’ stores all prefixes seen by the RIS
‘Aspath’ stores all aspaths seen by the RIS
‘Peer’ keeps all information about BGP peers
‘Updtlist’ is stand-alone and, as mentioned,
logs all insertion processes
