Master Git and a novice were walking to the market to collect alms.

The novice asked: "Master, what is the advantage of unstructured text over structured? Is it not mere adoption?"

Master Git said nothing and pointed to the first shop, kept by the old scrooge Postgre.

As they entered, Master Git said quietly, shaping his mouth funnily:

  SELECT weight/2 FROM shelf WHERE name = ''

Postgre, long weary of Master's wisdoms, took a weight of three from the nameless shelf and cut it unevenly. The whole piece he pressed into the novice's bowl; the larger part, he kept for himself.

Next stood a shop kept by a bright newcomer, Duck D'Bee.

Master Git repeated:

  SELECT weight/2 FROM shelf WHERE name = ''

Duck D'Bee smiled, carefully took an unnamed jar from a vertical stack and handed over one piece and half of another.

Their journey ended at a giant abandoned building beneath a dead neon sign: ORCL. The door stood open. Inside, putrid odour and dust lay upon deflated balloons and faded banners saying A.I. The shelves were still full of unmarked boxes.

Master Git shouted into the dark:

  SELECT weight/2 FROM shelf WHERE name = ''

Silence was the reply. At this point the novice became enlightened.
