The eXtremeDB is a real-time in-memory database system (IMDS) for a wide range of high performance, small size, tight storage, 0 memory allocations or several servers and embedded applications.
The development of eXtremeDB is entirely based on ANSI C and can be run on a variety of operating systems, including desktops, servers, embedded operating systems, and so on. eXtremeDB has no dependencies on the operating system, compilers, processors, or even on bare-metal without operating systems.
eXtremeDB is available in a variety of versions:
1, memory version-the use of memory storage, to avoid the disk I/O overhead, save the file system cache overhead, the system as much as possible to reduce the cost of CPU instructions.
2, memory and disk hybrid version-provides a dual engine of the database, not only supports all the features of the eXtremeDB Memory edition, but also supports persisting the database in the disk file for data persistence.
3. Financial Edition-supports all features of the eXtremeDB Memory edition, while using a columnar layout for financial data Store time-series data and store "normal" data with traditional row-based layouts, making full use of CPU-level/Level two caches to process data.
eXtremeDB Series of products in addition to basic database functions, there are such as SQL module, Transaction log module, cluster module and so on.
e Xtremedb is widely used in telecommunications, finance, power, rail, air, aviation, and aerospace with excellent real-time performance and good reliability. military and other real-time requirements in the field of extreme.
