Hi everyone,

I'd like to ask any insights from you especially those who've been to 
e-commerce developement with jsp of course.
We have here some accounting apps like payroll, inventory and etcetera; 
and suggested to run them on the browser so the customer
will able to use and rent them online. So we started thinking of making 
these into servlets and jsp. What we did so far was to have
a database on the server side that will track all the usernames who will 
use the system so that only those who have registered in the system will
able to use the modules. But the problem is that the database of each 
modules doesn't have any username field that will identify that which 
data are for
a particular user; which the system should keep the database of one user 
so that he can still use the database next time.
So what do you would be the good approach to implement database 
accessing that will be used for multiple users? Would that be a good
idea to have a database file for every user ? any ideas????

Thanks in advance.
