ObjectScript is a procedural programming language that can be used to write server-side code on the InterSystems IRIS® data platform. ObjectScript source code is compiled into object code that is highly optimized for operations typically found within business applications, including string manipulations and database access.
One of the unique aspects of ObjectScript is its underlying storage structure, known as globals. Globals can be thought of as persistent multidimensional sparse arrays. ObjectScript allows you to access your data directly from globals, but also allows you to access that data through its native object and SQL support.
