ABSTRACT
“Design and Implementation of an Online Interaction Forum for NITC” is an online
forum dedicated to NIT Calicut community. The system provides interaction among
students, faculty members and staff.
Users can subscribe to groups of their choice. In a subscribed group, they will be
able to post new topics and reply/comment on existing ones.
A topic thread structure will be followed within a given group. Based on the
category of user - student (UG/PG/Ph.D.) / faculty member / staff / admin, there
will be some default groups for them. He/she can subscribe to many other open
groups. There will be some groups to which only users of a certain type are allowed.

CHAPTER 4 – IMPLEMENTATION
The system is implemented in Ruby on Rails web framework. The first design
choice was to make the system on an MVC framework. Ruby on Rails is a very
robust, scalable and rich framework. The feature of this framework are – high
portability, can be used with variety of databases (Relational DBMS like Sqlite,
MySQL; Object oriented databases like Postgres), can be ported to different
webservers like apache, NGINX; can be run on both Linux or Windows operating
systems. The major challenge in the implementation has been the proper user
session handling.
