CISE Experimental Partnerships: Evaluating Real-Time Database Protocols

99- 00895 Stankovic，John A. CISE实验合作伙伴关系：评估实时数据库协议许多实时应用程序在其数据需求方面变得非常复杂。 敏捷制造和空中交通管制等应用的数据涵盖了从低级控制数据（通常从传感器获取）到高级管理和业务数据的整个范围。 在这样的应用程序中，来自所有级别的数据的无缝集成可以提供很大程度的整体效益。 此外，在这些应用程序的数据和处理层次结构的所有级别中，实时要求比比皆是。 当前的数据库不具有时间认知能力，并且在这些应用中表现不佳。 正因为如此，学术界和工业界对实时数据库的研究都有了显着的增长，许多商业产品也开始出现在这一领域。 这项工作建立在以前的模拟研究，确定了一些新的解决方案，在实时并发控制，实时事务调度，准入控制和资源管理。 研究建立在这些新的解决方案，以及新的想法，增强的对象模型，开发反射信息，和统一的多媒体服务质量资源管理模型。

Applications such as agile manufacturing and air traffic control have data that span the spectrum from low level control data, typically acquired from sensors, to high level management and business data. In such applications the seamless integration of data from all levels can provide a great degree of overall benefit. Further, in all levels of the data and processing hierarchy of such applications, real-time requirements abound. Current databases are not time cognizant and do not perform well in these applications. Because of this there has been a significant increase in research in real-time databases in both academia and industry and many commercial products are beginning to emerge in this area.This research involves prototyping and evaluating a novel real-time database system. The work builds upon previous simulation studies that identified a number of novel solutions in real-time concurrency control, real-time transaction scheduling, and admission control and resource management. The research builds on these novel solutions together with new ideas on an enhanced object model, exploitation of reflective information, and a uniform model for multimedia quality of service resource management.
