Description: eXtremeDB完全工作在主内存中，不基于文件系统，减少了诸如磁盘访问、文件I/O操作、缓存同步等开销，使得eXt remeDB的存取速度提高到极限；通过数据库定义语言面向应用系统定制的API使得eXtremeDB能够面向应用最优化；事 件触发、字段优先级等特色使得eXtremeDB管理实时数据时具有确定性。
eXtremeDB根据用户需求定义的API使得eXtremeDB与应用程序无缝集成。因此，eXtremeDB不仅在系 统中嵌入，而且“嵌入”在应用程序中，是一种真正的嵌入式实时数据库。在资源紧凑的系统中，eXtremeDB基本内存开销在6 0K到100K左右；对于大量实时数据需管理的情形,eXtremeDB最大一表格的记录总数可以达到2,147,483,64 7条。
eXtremeDB直观易用的，使您在零学习周期的情况下使用它管理实时数据。不论是VxWorks、WinCE、嵌入式Lin ux还是UNIX、Solaris，eXtremeDB都能出色地进行数据管理。
-eXtremeDB entirely in main memory, it is not based on the file system, such as reducing disk access, file I / O operations, cache synchronization overhead, making eXt remeDB access speed to the limit; Through the database definition language-oriented application system customization API to make eXtremeDB Application-oriented optimization; trigger events, such as field-level priority eXtremeDB characteristics makes real-time data management certainty.
