In-memory and Persistent Database Management System
Designed to be a powerful tool for the professional developer.
eXtremeDB: an in-memory and persistent database management system.
The eXtremeDB database management system was originally designed and optimized to be an in-memory database system (IMDS) with direct data manipulation. Storing and manipulating data in exactly the form used by the application removes overheads associated with caching and translation. On embedded platforms (e.g. ARM, PowerPC), typical write accesses are at the level of a few microseconds, or less, and read-only access is sub-microsecond. (Review our independently audited STAC benchmark test results .) When used as an embedded database system, the engine is reentrant, allowing for multiple execution threads, with transactions supporting the ACID properties, assuring data integrity.
In addition, eXtremeDB makes it easy for developers to combine the strengths of on-disk and in-memory database systems. Databases can be all-in-memory, all-persistent, or have a mix of in-memory tables and persistent tables. This unparalleled flexibility enables developers to tailor data management in order to optimize applications for speed and persistence, and make intelligent tradeoffs between cost-efficiency, power consumption, and physical space-conserving data storage hardware.
Data management where you need it
eXtremeDB can be utilized as an embedded database management system (typical in embedded platforms for Industrial Control, Aerospace/Defense, Consumer Electronics, and Network/Telecom gear), or as a highly scalable client/server architecture able to be distributed through sharding to gain maximum advantage of multiple cores, CPUs and/or servers (typical for High Performance Computing and Financial systems in private or public clouds).
