Tetrad Theories

Here is a table to describe some of the tetrads we have discussed so far in this blog.


The first column is our friend Structured Query Language (SQL). The second column is the four components of physiological and psychological health. The third column is the tetrad of McLuhan’s Laws of Media. The fourth column are the Zachman Framework’s four perspectives. The fifth column are the first four Structured Development Lifecycle (SDLC) phases.

The rows in the table correlate the similar facets of each of the tetrads. I will go into detail in a later post. How does energy, matter, location and event correlate? How do the Secrets of the Universe of Discourse correlate? How does data, information, knowledge and wisdom correlate? How does colon classification correlate?

Take a moment and let yourself stretch.

Oratory, Literacy and Digitality

I just finished reading a post at www.robertbleckman.blogspot.com and I am amazed at what myth passes for sound thought. Apparently, “Media Ecologists” are discussing the rise of a negative “second orality” which is a great deal of hogwash. The concept of a second orality is also raised by Ray Bradbury in Fahrenheit 451. What he and media ecologists don’t seem to recognize is the amount of trash oratory the listening public was consuming prior to the advent of trash literature and the amount of trash literature the reading public was consuming prior to the advent of trash television. If the pareto principle holds true 80% of all the media content out there is crap including the internet and your blog and mine. What is actually occurring is the literati of the present are being replaced by the digerati of the future. Marshall McLuhan is probably spinning in his grave when someone wanes sentimental about literacy.

Digital technologies are relieving us of much of the effort required to communicate. Literacy is now only one tool in the toolbox. Our children will communicate in ways we cannot even imagine. And it will be better. Adhering to outmoded means of communication will only result in our young people falling behind. Instead of practicing literacy Luddism look forward to the evolution of digital ecology.

McLuhan Revisited

I had a very good discussion today with a biochemist who is working for the federal virology lab in Winnipeg, Canada. We discussed Marshall McLuhan and he pointed out an error in how I was interpreting McLuhan and applying it to the Zachman Framework. He explained that I had to think of the data as the message and the network as the medium. He used a transportation system as an example where the people were the data and the vehicles were the packets in the transportation network.


As you can see, now the message and the medium have a place in the framework.

The Data Is Only Part of the Message

Marshall McLuhan is famous for his statement, “The medium is the message.”  In McLuhan’s definition of “medium” we get the broadest possible scope.  The media that McLuhan describes encompasses any “thing”, any “form” that can be used to communicate.  And I feel that McLuhan’s definition is more suitable for the definition of the interrogative “what” in defining a system than John Zachman’s “data”.  Data is too often restricted to digital media and most computer systems deal with media outside of this scope.  Therefore, I propose altering the Zachman Framework Abstract to use the term “medium” instead of “data” and calling the result the “McLuhan Framework”.


From here on in we don’t talk of a “data model” we talk of a “media model”.
