DATABUS

A third generation business application language also known as Programming Language for Business (PL/B), although starting out as a propriety language it has survived the onslaught of fourth generation business languages and the disappearance of its original developer due to how English like it is, on a superficial level some ways resembling some fourth and fifth generation languages. Almost unknown outside of the USA.

Due to its use of a rather generic name, we have the same problem with DATABUS as we have with PILOT while searching on the internet, it is very hard to actually find anything relating to the language and its implementations.
