The Birth of JOIN: Chapter 2

Rockwell Space Division

The monochrome screen flickered as the data flowed.  Men gathered around the monitor as if it was a shrine.  The tension was real.  Without fanfare a message appeared on the screen that said “IMS READY”.  The first computer based DBMS was operational. 

Lunar surface

One billion people held there breathe.
The landing strut touched the powdery surface and kicked up a small cloud of the alien substance.  216 parts on each of the four “feet” groaned under the sudden stress.

“I’m not!  I am just publishing a data model for data banks that I believe will solve a lot of problems and firmly place data management on sound mathematical ground.”

“I don’t think so”
“Did you find out what a Relation is?”
“No sir.”
“Oh well, never mind.”
