Multi-Tier Integration Challenges

• Good mappings and interfaces to provide object-relational objects to OOPLs
  • Java, C++, Smalltalk, others
  • Full query support in addition to navigation

• Challenges in querying and caching
  • Intelligent querying over cache + database
  • Correct and efficient caching of view objects

• Update-related challenges
  • Triggers and constraints of all types
  • View objects (both directions)

• Method execution on client or server
  • Java should be very useful here
