Hi all,
I have a question regarding the architecture to follow in the
web
applications. our application is going to be on the net and
the
number of users will be 20 to 30 at a time.we plan to use
JSP and Bean and the flow we thought is something as
below.
jsp -> bean -> businessObject -> sqlclass -> DB
FYI, we will be having number of beans,businessClasses and
sql classes.All the parameters will be passed as object
(dataObject) from bean to sqlclass.There will be 'n' number
of dataObject equivalent to the tables in the DB.
we are worrying about the performance because of the net
slow in some countries.
my question here is that does this architecture(having 5
logical
layers) will make the process slow? if so what can be the
best
application architecture for this scenario?
I have an another question regarding populating the values
from db
to the screen.for example i have to show some values in the
list,
should i have to fetch each and every time whenever the page
is loaded?
or keep it in the session scope and show it ?
If i keep it in the session , how do i get the latest value
if it is updated
in the DB through some other user?
Thanks for your time,
with regards,
rathna.
