uber nerdy stuff from my ongoing research: (which has to do with
  humanity and how we think) An unsung hero from before I was
  born: The guy that came up with "many to many" relationships in
  databases, basically the GOTO for databases.* While modern
  programming/database style hates many-to-many and GOTO
  statements, this "on demand" way of thinking that can handle
  disorganized 'anythings' is exactly the kind of direction
  computers and information services need to go, and have been
  going.*** So if I had a hat, my hat's off to [1]#CharlesBachman
  who deserves a Hashtag, for without him, none of us would even
  be able to conceive of a hashtag even existing. Without him,
  it's likely everything would be super-organized and
  hierarchical, which is the direction things had been going back
  in that day. That's fine and all, but there's needs to be a way
  to "break out" of the structure otherwise no innovations will
  ever occur. Via:

  The Network Database Model was invented by Charles Bachman in
  1969 to enhance the existing hierarchical database model. He
  created this model to increase the flexibility and make it less
  difficult to understand. To make this change Bachman developed
  the Network Database Model to allow multiple records to be
  linked to the same owner file creating a many-to-many
  relationship rather than a one-to-many. These many-to-many
  relationships were formed because one owner can linked to many
  member files and vice versa. To make the process faster Bachman
  also created these relationships to provide a relation between
  records using direct pointers, which is the fastest method of
  traversing (travel across) a network database." Interesting that
  what's new is old. https://en.wikipedia.org/wiki/Network_model
  Relational databases have been all the rage for the past 35
  years but starting a few years ago, Google, Apache and all the
  big whigs have been resurrecting an old idea and calling it new.
  I love it :P* "Look guys, it's NEW!" - no no, Google, etc - it's
  not new.
