Database system is used to store the data
  • fast retrieval of data (indexing)
  • language to query and manipulate data
  • simultaneous access by multiple users
Database keeps information about the components - not the final VRML form - semantic modeling
  • easy and powerful update
  • more compact storage
VRML representation is created dynamically
  • result is up-to-date
  • multiple views on the same data are possible
  • queries can select parts of the data
