General Heterogeneity Problem

• Typical DBMS solution

  • Object-relational: support for user-defined types
  • But often need native support for performance
  • Specialized tools: i.e., video db, image db, geographic db. Good for one type at the time

• Google also focuses on specialized tools

  • Are specialized tools the answer?
  • How about federated search across all types?
  • How about providing more than search?
