【摘要】 随着信息技术的发展,大型信息系统的使用越发广泛。信息管理系统的管理弹性也有着很大的提高,主要表现在管理的信息量和信息维度的扩充,并且在用户使用个性化和管理个性化的要求下,信息管理系统的设计弹性要求越来越大。而系统的弹性最突出的两个方面正是系统流程的弹性和信息维度的弹性。传统的信息维度的设计和维护往往是静态的,一旦有变化必须由设计人员对变化进行分析,同时由开发人员进行代码修改、数据库修改等,对于数据流程较长的大型系统这种变动简直就是灾难,而对于用户的管理需求又是十分必须的,因此动态信息维度的必要性越来越突出了。本文首先分析了信息维度的存在的现状,再进一步分析信息维度由静到动的必要性；在阐述传统系统设计中静态信息维度的弊端后,提出一套优化的信息维度设计方案：将信息维度进行静态和动态划分,对动态信息维度进行分析和共性的提取,并对关键技术——动态信息维度的存储、维护、应用效率进行深入分析、研究。接下来建立动态信息维度数据存储模型,实现动态信息维度的维护和动态信息维度的应用等工作。论文的最后,对该技术实现的可复制性进行论证,并对实现结果进行应用效率验证。信息维度的可变性、易变性在管理系统中一直是一个值得探讨的问题,动态信息维度可行性、稳定性、可复制性和实现的代价都是需要考虑的问题,动态信息维度的研究和实现为解决这一问题提供了一个可实现的方法。更多还原

【Abstract】 Large information system useful at this stage, more and more widely. In the large-scale management information management system has greatly improved elasticity, mainly in the expansion of information and information dimensions of the expansion, and the user demand for personalized and individualized request, the information management system requires more and more design flexibility. The flexibility of the system’s two most prominent process are the flexibility of the system and information dimension of flexibility. The information dimension of traditional design and maintenance are often static, once there is a change must be changed by the designer to analyze, Developers need to code changes, database modifications, etc..However, this change in large systems is simply a disaster, and this requirement is very necessary for the user. Therefore, the need for more dynamic information dimension highlighted.In the first part of this article, the author analyzes the status of the existence of the information dimension. Next, analyze the information dimension of the transformation from static to dynamic need. In explaining the traditional dimensions of system design drawbacks of static information, the proposed dimensions of an optimized design of information:dimensions of information by the static and dynamic, dimensional analysis of dynamic information to extract common, depth analysis of key technologies, research. Next, dimensional information to create dynamic data storage model, dimension of dynamic information and dynamic information dimension of the maintenance application, and so on. End of the article, implementation of the technology to demonstrate reproducibility, applied to achieve the results validate the efficiency of.Information dimension variability in the management system has always been a question worth exploring, and the feasibility of dynamic information dimension, stability, and realize the cost of reproduction are issues to be considered, dimension of dynamic information and implementation to address this issue provides a method of achieving.更多还原
