Basically there are a group of people working on
Information Systems applications, and have underlying
concepts of Information Theory.
Some regard the problem as a simple engineering activity
with information and data being interchangeable, while
others say that such a view cannot produce anything but
faulty, flawed systems and can ultimately lead to systems
failure.
It is, perhaps, more of an Information Systems area, but
the underlying principles/definitions of what information
is/are(??) and can be usefully viewed as are an issue within
the discipline.
My opinion has never particularly wavered from DNA as a code
beign an over-used analogy that has come to be accepted as
a fact -- DNA is a complex chemical, that forms part of
an incredibly complex reactive environment .... but's
it not information in an Information Theory sense (even
when viewed just as data transmission).
