Caché ObjectScript (COS) is a part of the Caché database system sold by InterSystems. The language is a functional superset of the ANSI-standard M (i.e. MUMPS) programming language. MUMPS programmers can run existing MUMPS routines under Caché with little or no change. The original scripting language for Caché, Caché ObjectScript is an object-oriented language. One interesting feature of Caché ObjectScript is that it enables the intermixing of data access methods – developers may view data as objects, as relational tables (using SQL), or as multidimensional arrays.
