Laguna Beach Summary

February 1988

Bernstein, Dayal, DeWitt, Gawlick, Gray, Jarke, Lindsay, Lockermann, Maier, Neuhold, Reuter, Rowe, Schek, Schmidt, Schreff, Stonebraker, Ullman

future db apps
Future DB Apps
  • CASE
  • CIM
  • Images
  • Spatial
  • IR
future hardware environment conclusions
Future Hardware Environment Conclusions
  • DB systems would continue to consume hardware resources as fast as they occurred
  • Special purpose DB machines were a dead end
future software environment conclusions
Future Software Environment Conclusions
  • DB and OS types would continue to do battle
    • “we will be stuck with current OS interfaces for a long time just as our clients are stuck with SQL”
  • 4GLs would solve the PL/DBMS impedance mismatch
  • PROLOG+DBMS will yield nothing of lasting value
    • Too many groups doing the same thing
extendible db managers
Extendible DB Managers
  • Heated debate on OR vs. Toolkit (no conclusions)
  • Heated debate on OODBMS
    • “misguided”
    • “highly significant”
    • Guess who was on which side of this debate
    • Approach was lacking a clear definition of the approach
active databases and rule systems
Active Databases and Rule Systems
  • Group strongly endorsed DBMS support for triggers, alerters, constraints with high performance
  • No need for general recursive queries (analogy drawn between its fate and the fate of nth normal form research)
end user interface
End User Interface
  • Universal consensus that we needed better user interfaces to data bases
  • Lamented lack of research
    • Difficult of publishing papers
    • Reviewers hostile because they lack RGE
    • Need to “demo or die”
    • Lack of toolkits (e.g. X11)
single site db technology
Single Site DB Technology
  • Hardware trends would require rethinking optimization, execution techniques, run time
  • CC was dead as a research topic
  • Strong support for parallel DBMS research
  • Little support for new access method research (except spatial)
distributed dbms
Distributed DBMS
  • Enough research. Commercialization was underway
  • Key remaining problems were administration of 50,000 node systems
miscellaneous topics
Miscellaneous Topics
  • Important to work on “no knobs” physical db design tools including index selection, load balancing of tables across disk arms, …
  • Some need for better logical design tools
  • Database support for continuous streams of data
  • No more data models please
  • Data translation was a solved research problem
  • Better support for information exchange
