2
Things that wont change

• Large databases
• Biology
• Astronomy
• Personal information management (Stuff Ive
  Seen)
• High-level query languages
• Data independence

3
Things that will change

• Fixation on performance
• Will dumb down implementations based on
  plentiful hardware more emphasis on usability
• Prediction ICDE/SIGMOD/VLDB 2020 papers accepted
  without performance sections (!!!)
• Artificial boundaries in data management
• Prime example Structured vs. unstructured data
• Boundary inherited from the previous millennium!
• Relational model and operators
• Will be generalized to handle unstructured data
• Unified data store

Applications

• Content management, PIM, life sciences,
• Used car marketplace
• Find all bright red ford mustangs that cost
  less than 20 of the average price of cars in its
  class
• Characteristics of queries
• Keyword search (for ease of use)
• Complex query operations (information synthesis)
• Want to see ranked results!

Summary

• Shift towards unified data management
• Example structured and unstructured data
• Conventional arguments about performance
  degradation due to unification will not hold
• Feasible!
• Initial steps
• XRank (ranked keyword search over XML)
• TeXQuery (query language for DB and IR)
