In I.T you hear interesting stories. Not always nice things that happen to companies. Things like data loss etc, mistakes made etc.
Sometimes they are amusing.
One sporting organisation in Australia developed an A.I. Recorded information (game results etc) they required. They queried it on who won a specific match (a major one), and it got the results wrong. A lot of queries were incorrect.
The issue was with how they indexed their data. Basically, how it was broken up. With data protection and storage, this is done out of the box. Often, you do not need to specify the strategy.
