Formed in 1996, M/Gateway Developments have a long history of creating technical interface and application frameworks for M-based technologies such as YottaDB. Focusing primarily on the web, M/Gateway created the first HTTP gateway for M, and through that gateway, a development environment. As these solutions were well received, M/Gateway subsequently created new free / open source software (FOSS) solutions taking advantage of newer web technologies: mg_web provides the base layer linking the three most popular web servers (Apache, Nginx, and IIS) to YottaDB and, layered above this, mg_web_server to create HTTP/REST-based services in YottaDB. An even higher Web Application development framework – Enterprise Web Developer (EWD) – was used to develop what is, to the best of our knowledge, the world’s largest Internet-based clinical application. A number of other large web-based M applications around the world rely on this and other M/Gateway technologies.

In 2011, M/Gateway were also responsible for the first Node.js solution for M. In 2019, M/Gateway created a multi-language free open/source access to M platforms including YottaDB: mg-dbx. mg_dbx delivers high throughput access from Node.js to YottaDB. Layered on top of mg-dbx is an advanced framework for creating high-performance Node.js applications using YottaDB as the database: QEWD.js. A special feature of QEWD.js is the projection of YottaDB as a persistent JSON store for seamless persistence of JavaScript Objects.

M/Gateway also provides a range of tried and tested, high-performance, high-reliability language bindings that allow developers working in other environments to take advantage of the YottaDB database. Currently these provide YottaDB language bindings for PHP (mg_php), Python (mg_python), Go (mg_go) and Ruby (mg_ruby). Full support for YottaDB’s Transaction Processing is included in all our language bindings. Finally, M/Gateway have created a generic SQL/ODBC engine for M databases – mgsql. This FOSS engine’s ODBC driver opens YottaDB data to the huge range of Windows based data-analysis tools.
