Innovative Routines International (IRI), Inc. is an American software company first known for bringing mainframe sort merge functionality into open systems. IRI was the first vendor to develop a commercial replacement for the Unix sort command, and combine data transformation and reporting in Unix batch processing environments. In 2007, IRI's coroutine sort ("CoSort") became the first product to collate and convert multi-gigabyte XML and LDIF files, join and lookup across multiple files, and apply role-based data privacy functions (including AES-256 encryption) for fields within sensitive files.
