Memory resident

To install itself memory resident the virus gets access to the EXPLORER .

为了自身能够内存驻留，这个病毒取得了对EXPLORER。

Classification , as an important field in data mining , has been researched earlier in statistics , machine learning , nerve net and expert systems . But most algorithms are memory resident , typically assuming a small data size .

分类作为数据挖掘的一个重要研究课题，在统计学、机器学习、神经网络和专家系统中得到了较早的研究，但其中大部分都是内存驻留算法，通常假定数据量很小。

It was also a memory resident file infector .

它也是一个记忆体驻存档案传播者。

So the virus installs itself memory resident as a component of EXPLORER .

所以这个病毒将自身驻留内存就象EXPLORER.EXE进程的一个组成部分一样。

Traditional database can 't satisfy those requirements at some field , so the memory resident database ( MMDB ) comes true .

传统的磁盘数据库在某些领域已经不能满足需求。为了有更快的存取性能，能对用户的请求给予更快的响应，内存数据库应运而生。

Analysis shows that use of memory resident database , single-level storage structure and client data buffer cache will remarkably enhance the performance of the database system .

结果表明，数据库常驻内存，采用一体化的单一级储存结构，并在客户端缓存数据，能使数据库系统性能得到很大的提高。

And two applications are introduced in this paper . They are IP resource management , and VLR Mobile user data auto backup . They both build on Memory Resident Database .

以这些功能为基础本文介绍了两个移动资源分布式管理的应用，分别是：IP资源管理和VLR用户数据自动备份。

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 .

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。

Studies the update-in-place and append-only characteristics of trading transaction updating in trading data . Brings forward a crash recovery scheme for trading-oriented main memory resident real-time database . Presents a structure model of the failure recovery manager and discusses its working mechanisms .

论述交易事务更新交易数据的update-in-place和append-only特征，提出了面向交易主存数据库的一种故障恢复方法，给出恢复管理机构的模型，并讨论了该模型的工作机制。
