E-Commerce, What is it in broader aspect???

Hello there

I am doing my dissertation. and after going through some of the
literatures, I came up with E-Commerce is broader aspects does not
only means money transaction covering B2B or B2C or C2C issues. It can
be something that can be informational but also focusing on User
authentication issues.

I have choosen a topic of how an educational site can be fallen into
e-commerce category. My point is that universities websites where we
put some restrictions in having usernames and password that which give
some pre define information for the relevant users, also can come into
e-commerce website standard.

Can any one please guide me in further to this and recommend any links
that may be supportive to this idea?

Thanks in advance and for your time
Regards
