This research, sponsored through the Research Opportunities for Women (ROW) initiative, investigates main memory database (MMDB) design. Declining memory costs and demands for fast database access times have spurred great interest in the development of MMDB's, where all or major portions of databases reside in the computer's main memory. The Principal Investigator's previous research into the factors which influence effective, recoverable MMDB design has been embodied in the MARS database system prototype. The research conducted here will develop further the requirements and characteristics of design support, including such elements as the novel addressing scheme using a set associative access to the stable memory. The overall objective of the MARS project is to actually implement a prototype MMDB system based upon this initial design. While that project will take several years, the purpose of this funded research is to produce a much more detailed design of the system. The importance of this research is that, by eliminating input/output bottlenecks, main memory databases may greatly improve the performance of knowledge based computer systems. This project represents one of the first efforts aimed specifically at designing, implementing, and evaluating a MMDB prototype.

这项研究由妇女研究机会倡议（ROW）赞助，研究主内存数据库（MMDB）的设计。内存成本的下降和对快速数据库访问时间的需求激发了对MMDB开发的极大兴趣，其中数据库的全部或主要部分驻留在计算机的主内存中。首席研究员之前对影响有效的、可恢复的MMDB设计的因素的研究已经体现在MARS数据库系统原型中。本文的研究将进一步发展设计支持的要求和特征，包括使用一组关联访问稳定存储器的新寻址方案等元素。MARS项目的总体目标是在此初始设计的基础上实际实现原型MMDB系统。虽然该项目将花费数年时间，但这项资助研究的目的是对该系统进行更详细的设计。本研究的重要性在于，通过消除输入/输出瓶颈，主内存数据库可以大大提高基于知识的计算机系统的性能。该项目代表了专门针对设计、实现和评估MMDB原型的首批努力之一。
