Relational Databases
The main drive behind a relational database is to increase accuracy by increasing the efficiency with which data is stored. For example, the names of each of the millions of people who immigrated to the United States through Ellis Island at the turn of the 20th century were recorded by hand on large sheets of paper; people from the city of London had their country of origin entered as England, or Great Britain, or United Kingdom, or U.K., or UK, or Engl., etc. Multiple ways of recording the same information leads to future confusion when there is a need to simply know how many people came from the country now known as the United Kingdom.

A world without joy. World, struck by disease. The world of human evil and devilish despair. Abandon hope, because it disappeared in a shroud of chaos. Bow down before the demons come for their kingdom. But the characters are able to find a way to salvation. And if for this we need to arrange a bloodbath ... Let it be so!
