Raima's Relational database Key Features

Group 16010

Fast In-Memory, Hybrid or Persistent Storage

RDM designed from the ground up to take full advantage of memory as the storage medium. This makes it not only faster than disk-based DBMSs but also faster than competitors who added in-memory as an afterthought.

Platform Compatability

Develop once, deploy anywhere. Through Raima´s file format, you can mix and match operating systems and hardware. RDM runs on a wide range of operating systems, including Windows, Linux, Apple, Android or RTOS: Windriver, GreenHills, QNX or Embedded Linux.
Group 16010

High Availability

RDM supports local storage and data replication from an RDM database to another RDM database system, or to any other enterprise database vendor, fx. Oracle or Microsoft SQL Server through SymmetricDS. Data can be collected on the device and replicated to an enterprise system for big data analytics and BI.
Group 16010

Easy to Use

We focus on ease of use, providing out of the box project files for all the standard development environments. RDM is automated to manage database storage and essentially all the critical functions are self-managed and we support the OS and development languages you know.
Group 16010

Extended Flash Media Lifetime

RDM optimizes and minimizes the number of writes to the storage medium, prolonging the lifetime of the device. This means less maintenance is needed for the medium and less replacements over the lifetime of the application. Additionally, RDM performs better on these devices due to the optimizations it has.
Group 16010

Reliability

Before the release of RDM, many tests and methods have been developed to ensure a robust and usable product. This is due to the stability and robustness requirements for a database being much more stringent than many other types of applications.
Group 16010

Embedded Systems and Real-time Application

Fully supports real-time system performance. RDM has been designed to meet the zero-administration requirements of an embedded application, there is no need for a database administrator.
Group 16010

Full Feature SQL Support

RDM provides developers with all the benefits SQL has to offer. Fully-featured and enhanced SQL support, including SQL PL, Stored Procedure, and Triggers.
Group 16010

Multi-Core Scalability

Maintain performance by adding further resources as demands on the system increase. RDM supports any 32-bit and 62-bit hardware.
Group 16010

Decreased Time to Market

RDM’s architecture delivers the highest performance while simultaneously safeguarding data and maintaining full ACID compliance. For in-memory databases, Raima uses a completely unique internal format to take full advantage of the direct memory characteristics of random access, zero latency, etc. If the database is on disk, Raima instead uses another uniquely designed and optimized format to take into consideration the latency involved with disk usage. The new architecture also hides hardware platform specifics such as byte ordering in the new file format design, freeing developers to focus on other details.
Group 16010

Small Footprint

RDM is designed for small footprint environments. Developers can reduce the size to as low as 350K, depending on features and options selected.
Group 16010

Simple Administration

RDM is automated to manage database storage and essentially all the critical functions are self-managed. it frees up time to focus on other things than administration.

RDM Performance Benchmarks

RDM 14.1 performs better than any competitor within a multitude of systems and environments. In the industry standard TPC-B test, our disk-based performance is able to process over 2,000+ more transactions than our closest competitors. The following test is run on an AMD Opteron 6180 SE Dual Core 2.5 GHz 128 GB of DDR3 1800MHz RAM running Windows 10 on a Dell H700 SCSI hard drive.
