摘要
现代主流操作系统已经广泛采用了多线程技术 .首先论述了多线程的基本概念 ,然后着重分析了 3种主要的多线程实现方案 :内核级线程、用户级线程和混合策略 ,然后介绍了多线程技术的应用 .还结合面向对象数据库管理系统 NODBMS的实现 ,介绍了如何应用多线程技术实现多用户事务处理 ,并提出了一个基于多线程技术实现的对象式数据库查询优化算法 。
Multithread technology has been adopted in recently developed mainstream operating systems. Firstly the basic concepts of multithread are described. Secondly, three implementation methods of multithread mechanism that is user\|level threads, kernel\|level threads and combined approaches are discussed. Thirdly, application of multithread programming is introduced. Through the object\|oriented database management system NODBMS, how to use multithreads to realize multiple transaction processing is also introduced, and is proposed an effective query optimization algorithm of object\|oriented database system based on multithread technology.
