My experience is that I am not going to say anything
anymore against any database until I know the
application and business requirements together with
proper knowledge of these databases I am talking
about.
Every database can have very good usage for what is
the best for.
My experience was that Oracle did not cover many
simple things these smaller databases are providing to
you.
My main concern in the last 2 years was the speed of
reference lookups for the biggest telecom companies.
I could not believe that Oracle is failing on this
simple thing for unknown reason.
As Nuno Souto said Oracle did not pay any attention to
have slim version of Oracle probably because it is so
hard to do anything now when the code, features and
everything is intermingled together.
We needed to test Berkley DB, MySQL, TimesTen and many
others to evaluate which database to use for fast
reference lookups.
We picked TimesTen because it was 6 times faster in
lookups and used SQL. We needed the only one strong
reason to pick TimesTen. Other companies are using
MySQL, SleepyCat and others to do their jobs
perfectly.
Oracle of course has crazy algorithm inside the
database engine and inside the PL/SQL (associative
arrays) written in C but never exposed to the client
side, so making these small database engines living
nicely (not just for that reason, but it is very big
reason if you can save on the number of CPU's 6 times
on some particular business action).
At the end, every database is useful and good when
applied to the specific business requirements.
