多维联机数据分析模型和系统设计方法

联机数据分析是解决我国现行的实际统计工作中普遍存在的几个问题的有效方法。本文介绍作者根据实际统计分析需要设计的MOLDA多维联机数据分析模型,和基于MOLDA的多维联机数据分析系统的设计方法,包括描述业务问题的"业务空间"的设计,包含各种统计分析计算和建模工具的"方法库"的设计;说明数据来源的"数据源"定义,以及如何从数据源中获得分析方法所需数据的"数据连接、抽取、转换"定义。用户通过选择方法,切片、旋转和上卷、下钻等操作,可以得到企业或管理部门分析决策所需的各种信息视图。MOLDA可以应用在企业或部门的职能统计,综合统计和决策分析等各个方面。

Multi-dimensional OnLine Data Analysis Technique and Its Application

This paper presents an OLAP system model--MOLDA (Multi-dimensional Online Data Analysis). A method for analyzing and designing MOLDA model based OLAP systems is also provided. "Index dimension", "classification dimension", as well as "time dimension" are adopted in MOLDA. Various statistics, analysis and modeling tools are allowed to install into the method base. Operational data or aggregated data can be connected as MOLDA data resources. By selecting methods and multi-dimensional operations, managers and decision makers can acquire various views of information they need to make effective decisions. The goal to design a good MOLDA system is to make it possible "to provide 'just-in-time' information for effective decision-making.
