Tetrads: McLuhan’s Laws and SQL

I have been going over all the past material in this blog as I am now working on my book. One of the things I am clearing up is my understanding of McLuhan’s Laws of Media known as Tetrads. All that McLuhan discovered and I don’t mean to diminish his work is discover the four manipulations that are possible with any form of media including data.

McLuhan’s four Laws of Media were:

  1. Retrieve
  2. Enhance
  3. Reverse
  4. Obsolesce

The four correspoding manipulations are:

  1. Select
  2. Insert
  3. Update
  4. Delete

Please dismiss any past correlations I made between the Manipulations and Laws of Media with the Six Interrogatives.
