GT.M is a schema-less database engine with scalability proven in the largest real-time core processing systems in production at financial institutions worldwide, as well as in large, well known health care institutions, but with a small footprint that scales down to use in small clinics, virtual machines and software appliances. The GT.M data model is a hierarchical associative memory (i.e., multi-dimensional array) that imposes no restrictions on the data types of the indexes and the content - any schema, dictionary or data organization is entirely that implemented by the application logic. GT.M's compiler for the standard M (also known as MUMPS) scripting language implements full support for ACID (Atomic, Consistent, Isolated, Durable) transactions, using optimistic concurrency control and software transactional memory (STM) that blurs the distinction between databases and programming languages. Its unique ability to create and deploy logical multi-site configurations of applications provides unrivaled continuity of business in the face of not just unplanned events, but also planned events, including planned events that include changes to application logic and schema.
