Leading Database for Real Time Operating Systems (RTOS)

Built by Developers, for Developers

Raima Database Manager is an embedded relational database management system developed for applications with limited memory and connectivity needing high performance. RDM enables intelligent decisions to be made on the device level in near real-time.

An Embedded Database developed for applications that are:



RDM is designed for applications that require local storage if connectivity is lost, unmatched speed for real-time decision-making and reliability.

Resource Constrained

RDM needs only 350k of RAM and minimal CPU speeds to fully operate. With more power in the system, RDM will fully utilize it all to perform even faster.



RDM is automated to manage database storage and essentially all the critical functions are self-managed.

Database encryption, secure icon


AES encryption from 128 bit to 256 bit meets market demand for cybersecurity support and gives Raima clients peace-of-mind.

Handshake icon


ACID transactions guarantee that when changes to a database record are made, that data is correct and no data is lost.
