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

- Thanks for the reply - my particular application involves realtime data as
- in milliseconds between events...but with proper buffering I was hoping that
- some DBMS could keep up...I am talking about 40K events per hour maximum with
- data available for stats shortly after. shortly indicating minutes.
-
- Also - does anyone have any input as the how well Sybase deals with RPC's?
-
- Thanks in advance.
