GT.M是一个经过验证的具备工业强度的、支持事务处理的 Key-Value 数据库，特别为极限事务处理的场景使用。采用C/C++开发并在GPLv2协议下授权。GT.M™ Database Engine with Extreme Scalability and Robustness.
Rock Solid. Lightning Fast. Secure. No compromises.
GT.M is a 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 healthcare 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 - the application logic can impose any schema, dictionary or data organization suited to its problem domain.* 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 resolves the common mismatch 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.
Worldwide, GT.M is used in multiple industries, including finance, health care, transportation, manufacturing and others. GT.M supplies the processing power to the FIS Profile™ enterprise banking application.
最新版本：6.1
Virtually unlimited global variable sizes.
Transport Layer Security (TLS/SSL) for replication.
An easier path when FIPS 140-2 certification is required for encrypted databases.
Relink recursive: processes can explicitly link new versions of routines even when they have prior versions of routines with the same name already on the process stack.
SOCKET device support for local sockets (also known as UNIX domain sockets.
Faster database reads, especially when large numbers of processes (thousands) concurrently access a database file
