this paper utilizes decision theory, cybernetics and system according to function and the characteristic of the state-owned group financial accountant of holding company to discuss and worth related theories such as theory, is close to combine the reality of the state-owned group financial management and accounting information system of holding company, adopts to determine the nature, is with ration, sum up the method of deducing, enumerate case layer upon layer further, record system and processing for the state-owned systematic essential factor, system hierarchy of control and classfication in the group accounting information system of holding company to handle system, combined accounting form and accounting accounting center, information transmit the related problems such as system have carried out the thorough research of overall system, inference makes the modern systematic structural frame of the state-owned group accounting information of holding company that perfected scientifically, and reach following conclusion : first, accounting information is that the key, accounting information system of the information of business management is the strong support system of enterprise decision 外部竞争和内在要求的双重压力都表明企业集团构建科学完善的会计信息系统十分必要和迫切。本文根据国有控股企业集团财务会计的特点与职能,运用决策论、控制论、系统论和价值论等相关理论,紧密结合国有控股企业集团财务管理和会计信息系统的实际,采用定性与定量相结合、归纳推断的方法,层层深入,列举案例,对国有控股企业集团会计信息系统中的系统要素、制度控制体系、分类记载体系、加工处理体系、合并会计报表、会计核算中心、信息传递体系等相关问题进行了全面系统深入的研究,推论出科学完善的现代国有控股企业集团会计信息系统的构架,并得出如下结论:第一,会计信息是企业管理信息的核心,会计信息系统是企业决策的强有力的支持系统。
the ddg policy is targeted at improve the holistic metadata processing performance, and takes both balance degree of metadata and file system hierarchy into consideration . the ddg policy distributes metadata according to distribution granularity which is a directory hierarchy defined by a triple . our performance test results show that this policy is potentially more efficient than the other two types of policies under the workload that simulates real environments 我们提出的基于粒度的动态元数据分布策略以提高元数据处理整体性能为目标,综合考虑元数据分布均衡度和文件系统层次结构关系两个因素对元数据处理整体性能的影响,按照d-d-f粒度来划分名字空间和分布元数据,实验结果表明在模拟真实环境的负载下其性能优于动态随机分布策略和动态根子树分布策略。
