摘要
Dedicated tools have been developed at CDS in order to face the challenge of fast on-line access to very large astronomical catalogues. Powerful compression methods, keeping the direct access to the data on the basis of their celestial position, allow very fast queries; their usage for CDS services such as VizieR or Aladin is presented.
