STUDY AND APPLICATION OF MULTITHREAD TECHNOLOGY

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.
