15. Other Emerging Database Technologies
2
Deductive Databases

• Reasons
• Access to large amount of information for
  knowledge processing
• Efficient management of data and knowledge
• Intelligent processing of data
• AI / DB integration
• Knowledge-based systems
• Logic databases
• DDB relational model (facts) first-order
  logic (rules)
• Rules
• Inference engine
• Datalog (subset of Prolog rules)

3
Other Emerging Database Technologies

• Active Database
• Passive DBMSs
• New applications, such as process control, battle
  management, hospital patient monitoring, require
  timely response
• An active DBMS continually monitors the database
  state and reacts when predefined events occur
• Multimedia Databases
• Store multimedia information numeric data, text,
  bitmap images, raster graphics images, audio, and
  video
• Use appropriate display devices to present the
  information
• Applications
• Document management
• Education and training
• Real-time control

... Other Emerging Database Technologies

• Scientific and Statistical Databases
• Earth science data
• Space data
• Example The Human Genome Initiative (HGI)
• An international effort to determine the location
  of about 100,000 human genes
• DNA is a two linear strands wrapped around each
  other
• The DNA sequence (code) is a set of base pairs
• There are billions of base pairs
• A gene is a region of chromosome whose DNA
  sequence can be copied

5
... Other Emerging Database Technologies

• Spatial Data Management
• Model spatial dimension
• CAD, architect civil engineering and geological
  surveys applications
• Three common representations
• Solid representation
• Boundary representation (wire frame models)
• Abstract representation (above, near, behind, ...)

6
... Other Emerging Database Technologies

• Temporal Data management
• Time-varying information vs time-invariant
  information
• Applications project management, patient
  systems, maintenance history
• Support for time
• Time point
• Time interval
• Abstract relationship (before, after, during,
  simultaneously, ...)
• Temporal Relational Model (TRM)
• Temporal SQL (TSQL)
