Overview

GT.M is a hierarchical, schema-free, highly scalable database.

It is commonly used in Financial and Healthcare applications.

It is important to distinguish between:

The language and the database tend to be used together, but they do not have to.

It is possible to use the M Database from other programming languages.

Here we focus on M as a Database.

Main Features

The main features of M are:

  • It represents a hierarchical (tree) data structure.
  • Supports full Atomic, Consistent, Isolated and Durable (ACID) transactions.
  • Is substantially faster for transaction processing than traditional relational databases.
  • Sorts entries automatically as soon as they are inserted.
  • Imposes no restrictions on the application schema.
  • The schema is entirely implemented and enforced by the application.
  • Just as it is with other “schema-free” or “NoSQL” key-value databases.

Why M ?

Here are the some of the features that may lead you to use M:

  • Sparse data
  • When your records contains highly diverse fields.
  • When certain fields will be missing for a large number of records.
  • Unstructured data
  • When the data itself is not fitting a specific schema.
  • When the schema changes overtime. (for example, due to government regulations).
  • High availability
  • When you need to facilitate the development of continuously available applications with logical dual site operation.
  • Unlike other platforms, GT.M’s functionality allows a suitably designed application to be continuously available as it is upgraded, even when the upgrade involves a database schema change.
