I was reading the available papers (&
old messages in the Forum, too) about
this topic , and the following issues
arise :
Jdeveloper : the strong point in Forms
always has been the RAD approach :
without ** any ** PL/SQL or SQL
knowledge, one person can build in
minutes a real-working program capable
of Insert, Update & Delete information
in a
database table. And the best,
automagically this generated program
WILL use the best options for
performance, like ARRAY PROCESSING ,
BINDING vars, (in multiline blocks),
no REPARSE - the last two are FREE
with PL/SQL.
So, the questions : the JDev wizard
to generate a program IS comparable in
the current version of Jdev with the
Forms one ? The generated program IS
totally ready to
use, or no ?
And about the performance of the
generated program, how "smart" is the
wizard ? The main point here is , Java
is a generic (non Oracle-centric)
language, SO to receive the same
beneficts above cited (array proc,
binds, fewer parses) the program MUST
be coded according some rules
(only prepared statements, no missing
open/close, no uppercase/lowercase
diffs in SQLs, etc, etc), OR - better
option - the Java program must call
PL/SQLs packages. Are current JDev
doing it ? And about the future, are
Jdev people inside Oracle thinking
about this practical issues ??
Forms 9: the main question in my haed
about it comes from the mig paper, it
says :
"No business logic is executed on the
client; it is responsible for
rendering the screen. All logic is
processed on the application tier."
See, commonly "application tier"
intends "another machine", so the
network traffic between machines MUST
increase by a large factor, IMO :
in special I think about
whn-validate-xx triggers - in C/S apps
MANY user-enterable fields responds
to/critiques user actions IMMEDIATLY
after the user attempts to exit from
the field, this behavior is normally
DEMANDED by users, in my experience.
In this situations, HOW Forms 9 will
respond to it ? Forms have ANY kind of
optimization to this kind of traffic ?
And to current Forms 9 users : in
the common-garden Ethernet-100 (no
Gigabit) local network, HOW has been
the experience ? Too much net perf
problems ?
Regards,
Chiappa
