in-memory database (IMDB) allows for significant performance gains and a reduction in processing requirements when compared to older in-memory or on-disk implementations. Version 14.1 of RDM was released in Q1/18. The new release focuses on ease of use, portability, and speed. With Raima's new file format, you can develop once and deploy anywhere. Performance is increased by over 50-100% depending on the use case when compared to previous RDM releases. Raima has extended and improved SQL support, snapshots, and geospatial functionality. Version 14.2 of RDM was released in 2020. The new release has continuous focus on ease of use, portability, and speed. Multi-user Focused Storage Format: the updated database file format increase database throughput through a focus on locking contention prevention. Extended and improved geospatial functionality and a newly supported REST-ful interface have been added to the database server functionality. Version 15.0 of RDM was released Q2 in 2021. The focus of that release was speed, ease of use and new functionality. Custom generated time series support has been added to RDM. Also FFT support for data transformations. An administrative GUI is introduced. Product features Both the source code lines and features in Raima Database Manager and RDM Server are consolidated into one source code. RDM includes these major features: updated in-memory support, time series and FFT support, snapshots, R-Tree support, compression, encryption, SQL, SQL PL, and platform independence—develop once, deploy anywhere. RMD includes portability options such as direct copy and paste that permit development and deployment on different target platforms, regardless of architecture or byte order. The release includes a streamlined interface that is cursor-based, extended SQL support and stored procedures that support SQL PL; it also supports ODBC (C, C++), ADO.NET (C#), RESTful and JDBC (Java). Supported development environments include Microsoft Visual Studio, Apple XCode, Eclipse and Wind River Workbench. A redesigned and optimized database file format architecture maintains ACID compliance and data safeguards, with separate formats for in-memory, on-disk or hybrid storage. File formats hide hardware platform specifics (e.g., byte ordering). Download packages include examples of RDM speed and performance benchmarks. Transactional File Server (TFS) A software component within the RDM system that maintains safe multi-user transactional updates to a set of files and responds to page requests. The TFServer utility links to the TFS to allow it to run as a separate utility, allowing users to run RDM in a distributed computing environment. The TFS may
