Back in the discussion of putting SNMP data in databases,
I'd like to ask a more fundamental question.
Do people use SQL features ? I mean "SQL" (structured queries)
instead of just "Database" (store/get).
To be honest I'm not sure yet. The main point is that you never know what
way people are going to use the data. Far too often I have been frustrated
using a system because the designer didn't consider that other people might
have different needs and didn't bother putting a little bit of effort into
making something more generic (HPOV springs to mind for some reason). So I
wanted to see if it was possible. However I do anticipate some usage of
structured queries to help detect behavioral patterns and trends (OK I'm doing
a bit of hand-waving here but it's my time :).
A full SQL implementation is perhaps over the top but it's the only thing I
know of for doing ad-hoc queries (in reasonable time).
Actually, I think I will put some thought into exactly how I might use the
data and how easy/hard it is to extract. Glad you brought that up.
I was working on the same path as people already mentioned here
(collect with scotty, store in MySQL), when I realized that
*for my needs* there was no gain in using an SQL database.
I've since changed DBMS, and currently use berkeley db
straight from Tcl. This database just gives you a generic
(key,data) structure, which of course can accommodate
whatever you want to store.
The major advantage, I think would come from a temporal database,
since almost all of my data are associated with a timestamp.
However, I haven't found one I can readily use (and I doubt
there exists one).
How about a self-optimising declarative logic database, but look how long it
took SQL to reach the availability it now enjoys.
