InterSystems

InterSystems Corporation is a privately held vendor of software systems and technology for high-performance database management, rapid application development, integration, and healthcare information systems. The vendor's products include InterSystems IRIS Data Platform, Caché Database Management System, the InterSystems Ensemble integration platform, the HealthShare healthcare informatics platform and TrakCare healthcare information system, which is sold outside the United States. InterSystems is based in Cambridge, Massachusetts. The company's revenue was $727 million in 2019. InterSystems was founded in 1978 by Phillip T. (Terry) Ragon, its current CEO. The firm was one of the vendors of M-technology (aka MUMPS) systems, with a product called ISM-11 (an DSM-11 clone) for the DEC PDP-11 . Over the years, it acquired several other MUMPS implementations: DTM from Data Tree (1993); DSM from Digital (1995); and MSM from Micronetics (1998); making InterSystems the dominant M technology vendor. The firm eventually started combining features from these products into one they called OpenM, then consolidated the technologies into a product, Caché, in 1997. At that time they stopped new development for all of their legacy M-based products (although the company still supports existing customers). They launched Ensemble, an integration platform, in 2003 and HealthShare, a scalable health informatics platform, in 2006. In 2007, InterSystems purchased TrakHealth, an Australian vendor of TrakCare, a modular healthcare information system based on InterSystems technology. In May 2011, the firm launched Globals as a free database based on the multi-dimensional array storage technology used in Caché. In September 2011, InterSystems purchased Siemens Health Services (SHS) France from its parent company, Siemens. In September 2017, InterSystems announced InterSystems IRIS Data Platform, which, the company said, combines database management capabilities together with interoperability and analytics, as well as technologies such as sharding for performance.
