The issues involved in designing efficient checkpointing and recovery techniques for distributed/parallel computations have been extensively studied and are well understood; efficient solutions exist for this problem in this area. However, the issues related to checkpointing and recovery in distributed and mobile database systems as well as distributed object-based systems are not well understood. This project focuses on these issues. More specifically, this project will develop a theoretical framework that addresses the issues related to developing efficient checkpointing and recovery techniques for distributed and mobile database systems as well as distributed object-based systems. Based on the framework, efficient non-intrusive asynchronous checkpointing and recovery techniques will be developed for such systems.The important expected broader impacts of this project are: (i) an improved understating of the issues related to the design and implementation of fault-tolerant distributed and mobile database systems as well as distributed object-based systems; (ii) availability of efficient checkpointing and recovery techniques for building fault-tolerant distributed and mobile information systems as well as distributed object-based systems would help in building such systems; (iii) involvement of graduate students in the project will enhance their understanding of the issues related to the design and implementation of fault-tolerant distributed and mobile information systems and also help them acquire the tools and techniques for building such systems; (iv) the research results from the project will be presented in international conferences and also published in international journals which will benefit the researchers in both academia and industry; (v) the research results will also be integrated in a graduate level course.

设计有效的检查点和恢复技术的分布式/并行计算所涉及的问题已经得到了广泛的研究和理解，有效的解决方案存在于这个问题在这方面。然而，分布式和移动的数据库系统以及分布式基于对象的系统中的检查点和恢复相关的问题还没有得到很好的理解。本项目侧重于这些问题。更具体地说，这个项目将开发一个理论框架，解决有关开发有效的检查点和恢复技术的分布式和移动的数据库系统以及分布式基于对象的系统的问题。基于该框架，将为这类系统开发有效的非侵入式异步检查点和恢复技术，该项目的重要预期更广泛的影响是：（i）改进对容错分布式和移动的数据库系统以及分布式基于对象系统的设计和实现相关问题的理解;（ii）为建立容错分布式和移动的信息系统以及分布式基于对象的系统而提供有效的检查点和恢复技术将有助于建立这种系统; ㈢研究生参与该项目将提高他们对容错分布式和移动的信息系统的设计和实施相关问题的理解，并帮助他们获得建立这种系统的工具和技术;（iv）研究成果会在国际会议上发表，并在国际刊物上发表，使学术界和工业界的研究人员都能受惠;（v）研究成果亦会纳入研究生课程内。
