MUMPS is standard in places which deal with Intersystems, via Ensemble (integration system) and their Cache database. An intriguing stack of technologies: an old and 100% backward compatible programming language, an object-oriented (non-relational) database with direct access from the high-level language (M; they do not like it when you call it MUMPS), and quite a number of very good software engineers having worked on this system for 30+ years.
