Raima Database Manager™ (RDM)

High-Performance Embedded Database Technology

Raima Database Manager (RDM)™ is an embedded in-memory database developed for the IoT and edge market. It is fast and persistent, optimized for performance and reliability (see our performance testing benchmarks). RDM can be used through a call from it's extensive suite of API's including the C/C++ cursor, Java JDBC, and C# ADO.NET.

An optimized in-memory implementation allows for faster transactions and results to support enterprises that need the utmost speed and performance. Learn more.

Fully supports real-time system performance.  RDM has been designed to meet the zero-administration requirements of an embedded application. Learn more.

Small Footprint

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 but that is not required.

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

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

Through the use of SymmetricDS, Raima can store data on the edge and easily replicate that data to RDM or any cloud database.

By Developers, for developers.

Full featured and enhanced SQL support including SQL PL, Stored Procedures and Triggers.

Our Customer Support team is dedicated to provide fast, friendly and effective service. We also provide free support during your evaluation process to help you get the most out of RDM.

Automatic encoding and compression use 25% less disk space on average. You can also leverage our vacuuming. Learn more.

B-Tree, Hash, R-/R+ Tree, and AVL indexes are fully supported by RDM and available for users. Indexing with RDM.

Develop once, deploy anywhere. The file format allows direct copy/paste or movement from one device or platform onto another regardless of byte order or architecture differences. RDM can even run without an OS in a barebones configuration. Learn more.

Multi-Core Scalability

Maintain performance as demands on the system increase by adding further resources. Possible through SMP and thread support, plus the capability of scaling on more than one server.

Flexible Licensing Options

Raima has always made the RDM source code available at a reasonable cost. Raima and its experienced developers are proud of this code and don’t mind if you take a peek, or even step through it in your own debugging system. Source code comes complete with project files necessary for you to build it yourself.

Since RDM can be freely downloaded and licensed for application development at a very low entry fee until it is ready to deploy, and with source code availability, there is very little cost difference between Raima’s commercial licensing and Open Source with support or for commercial use.

RDM Core

This introductory package is typically used in applications designed for edge IoT devices, where performance and footprint are of great importance.  Experience direct access to a comprehensive and easy-to-use low-level cursor C API for ultimate control while also providing a C++ API for object-oriented programming.

DBeaver Advanced Mock-Data

In DBeaver you can generate random data (or “mock" data) for tables which looks like real data.

While the Community edition provides just basic data generators, the Enterprise edition supports many more additional generators and configuration including:

  • Names
  • Addresses
  • Credit cards
  • Domains and IP addresses
  • Custom regular expressions
  • Flexible numeric generators
