That is a very broad question.
As with any new development
project, the first thing you need to do is to define the requirements
for the system, in a very clear and unambiguous way.
system” could mean a lot of different things, and even if one gets the
idea of the required system, the features and specifics of its
functionality need to be defined.
After defining the requirements
you can start analyzing and designing, and after that, you can start
actually using Forms to create the applications.
Such a broad question cannot be answered here, sorry.
if you have specific questions or find problems when designing or building the system,
feel free to post them here on ITKE, and the community will try to help
