'''M''' is the short-name for the programming language [[wp:MUMPS|'''MUMPS''']] which stands for "Massachusetts General Hospital Utility Multi-Programming System". ~~MUMPS~~ predates SQL so it's the trendy "no-sql" before SQL. How hipster is that? Because M was developed around 1966 on the DEC PDP-7 (which didn't even have an operating system), M was an operating system of sorts and a database and a programming language all in one.

It is the database concepts in M that make it unique, not necessarily the programming language. The M database has been described as multidimensional and post-relational, both are true. It is this database, or Global structure that makes MUMPS unique, and difficult to understand.
