  24. I cannot tell from this post whether you are interested in "real_time"
  25. or "online_and_really_fast_time". Real time implies able to keep up
  26. with externally driven events, which implies extremely predictable 
  27. performance. None of the RDBMS's that I know of are very good at that.
  28. They tend not to have robust priority scheduling; and predictability
  29. doesn't go hand-in-hand with black box caching and ad-hoc queries.
  30. SYBASE is however a *very* good OLTP database.
