Scientific Databases (SDB)

• A Long-term mission started in 1986 which funded
  by CAS
• many institutes involved
• long-term, large-scale collaboration
• data from research, for research
• Collecting multi-discipline research data and
  promoting data sharing
• More than 350 research databases and 400 datasets
  by 61 institutes
• Over 60TB data available to open access and
  download

CAS Scientific Data Grid

• Based on Scientific Data Grid Middleware (SDG)
• SDG is built upon the Scientific Database,
  supporting to find and access large scale,
  distributed and heterogeneous scientific data
  uniformly and conveniently in a SECURE and proper
  way
• Building scientific data application grid
  according to domain requirements
• Integrate distributed data, analysis tools and
  storage and computing facilities, providing a
  uniform data service interface
• 4 pilot grids
• bioscience grid
• geoscience grid
• Chemistry grid
• Astronomy and space science grid

10
Function Framework of SDG

• A scalable and integrated data sharing
  environment
• Providing services for grid users, grid managers
  and resource provides
• Operating by the operation center, science
  gateways and data nodes
