All programmers should sudy and learn the relational algebra and the Codd Normal Forms. They should also study the horror of SQL and pray that they never have to use it.

It fills me with incredulity that _anyone_ thought that data access should be achieved through text statements that are compiled and executed in a running system. How many data breaches have been based on that dumb mistake alone?

Data access within a running system should always and only be accomplished through an API.
