MARS: The Design of a Main Memory Database (Computer and Information Science)

这项研究，通过研究机会赞助 妇女（ROW）倡议，调查主存数据库 （MMDB）设计。 不断下降的内存成本和对 数据库访问时间引起了人们对 MMDB的开发，其中数据库的所有或主要部分 存在计算机的主存储器中。校长 研究者对影响因素的先前研究 有效的、可恢复的内存数据库设计已经在MARS中得到了体现 数据库系统原型在这里进行的研究将 进一步发展设计的要求和特点 支持，包括新的寻址方案等要素 使用对稳定存储器的集合关联访问。整体 MARS项目的目标是实际实施一个 原型内存数据库系统的基础上，这一初步设计。而 该项目将需要数年时间，此次资助的目的是 研究的目的是对系统进行更详细的设计。 这项研究的重要性在于，通过消除 输入/输出瓶颈，主存数据库可能大大 提高基于知识的计算机系统的性能。这 该项目是第一批专门针对 设计、实现和评估一个内存数据库原型。

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.
