虚拟存储空间

设计了一个常驻内存的实时面向对象数据库系统（MMRT-OODB），利用WINDOWSnt操作系统内存管理技术，把整个数据库映射进虚拟存储空间，避免了数据结构的转化。

The memory resident real-time object-oriented database system ( MMRT-OODB ) was designed . Using the memory management technology of Windows NT operation system , the whole database was mapped into virtual storage space to avoid transforming the data structure .
