摘要： 在审计项目开展过程中，审计人员通常需要对被审计单位所提供的数据进行恢复，并在此基础上开展审计分析。由于不同数据库系统都有自己相对独立的存储体系，交换数据的格式也存在一定差异，因此在数据恢复过程中，审计人员不得不基于被审计单位的应用环境来构建分析环境，并完成数据恢复工作。

关键词： Database systems  

摘要： To survive in a highly competitive, rapidly changing business world, an enterprise needs information and communications technology (ICT) systems that can respond flexibly and quickly to the market. However, as ICT systems become increasingly complex, the need to reduce their management and operating costs increases. Databases, moreover, are ICT systems having high-reliability and high-performance requirements. The FUJITSU Integrated System HA Database Ready product integrates database technologies cultivated by Fujitsu over many years with advanced hardware. Providing "high-reliability and high-performance," "open-standards," and "ready-to-use" features, HA Database Ready can significantly reduce the costs of deploying, designing, and operating a database infrastructure. This paper introduces a fully redundant system that uses advanced hardware to support high-reliability and high-performance operation and Fujitsu's Smart Software Technology for performing a full range of tasks from system deployment to system operation, monitoring, and troubleshooting using a simple graphical user interface (GUI).

摘要： Rationale and Objectives: The objective of this study was to demonstrate that an intra-arterial liver therapy clinical research database system is a more workflow efficient and robust tool for clinical research than a spreadsheet storage system. The database system could be used to generate clinical research study populations easily with custom search and retrieval criteria. Materials am:Methods: A questionnaire was designed and distributed to 21 board-certified radiologists to assess current data storage problems and clinician reception to a database management system. Based on the questionnaire findings, a customized database and user interface system were created to perform automatic calculations of clinical scores including staging systems such as the Child-Pugh and Barcelona Clinic Liver Cancer, and facilitates data input and output. Results: Questionnaire participants were favorable to a database system. The interface retrieved study-relevant data accurately and effectively. The database effectively produced easy-to-read study-specific patient populations with custom-defined inclusion/exclusion criteria. Conclusions: The database management system is workflow efficient and robust in retrieving, storing, and analyzing data.

摘要： Background: When studying the genetics of a human trait, we typically have to manage both genome-wide and targeted genotype data. There can be overlap of both people and markers from different genotyping experiments;the overlap can introduce several kinds of problems. Most times the overlapping genotypes are the same, but sometimes they are different. Occasionally, the lab will return genotypes using a different allele labeling scheme (for example 1/2 vs A/C). Sometimes, the genotype for a person/marker index is unreliable or missing. Further, over time some markers are merged and bad samples are re-run under a different sample name. We need a consistent picture of the subset of data we have chosen to work with even though there might possibly be conflicting measurements from multiple data sources. Results: We have developed the dbVOR database, which is designed to hold data efficiently for both genome-wide and targeted experiments. The data are indexed for fast retrieval by person and marker. In addition, we store pedigree and phenotype data for our subjects. The dbVOR database allows us to select subsets of the data by several different criteria and to merge their results into a coherent and consistent whole. Data may be filtered by: family, person, trait value, markers, chromosomes, and chromosome ranges. The results can be presented in columnar, Mega2, or PLINK format. Conclusions: dbVOR serves our needs well.

摘要： 强制访问控制是保护数据库管理系统安全的有效机制.DMOSMAC是一个依赖于安全操作系统实现强制访问控制机制的数据库管理系统.在分析该系统实现的基础上,对该系统进行了形式化分析.给出了信息流的概念,将信息流集合作为被验证系统状态的一部分.信息流集合始终是一个递增的集合,利用信息集合流可防止删除等操作的证明被绕过的可能,保证验证过程的严密性.在信息流的基础上提出了一种对系统代码进行抽象、抽取的形式化分析方法.即抽象DMOSMAC系统状态,从源代码中提取操作规则,将BLP模型中的状态、访问规则分别与DMOSMAC系统的状态、操作规则建立映射关系,BLP模型中简单安全性和*-特性转换为面向信息流的状态不变式,继承BLP模型的相关安全公理和定理进行分析和证明;最后用定理证明器COQ进行安全性证明的方法.
