【摘要】 随着数据仓库和OLAP技术及数据挖掘技术研究和开发的不断深入，决策支持系统(DSS)的发展也跃上一个新的台阶。开发综合决策支持系统主要以数据仓库(DataWarehouse)技术为基础，以联机分析处理(OLAP)和数据挖掘(DataMining)工具为手段进行实施。DSS不是一种通用的产品，而是一个解决方案。实施DSS，通常遵循总体规划、分步实施、迅速受益、不断完善的原则。 本文首先介绍了数据仓库的概念、实现和发展，数据挖掘的概念、方法和技术等。接着，将上述理论运用于实践，基于政府税收部门面临的新挑战：提供更好的客户服务，加强征管力度，改善资源管理，并准确预测相关法规及政策的效果。本文提出了地税发票综合业务分析决策系统的解决方案。该分析决策系统通过运用OLAP技术和数据挖掘技术对地税发票综合业务数据仓库中的数据进行多方位，多层次的分析，为税务机关对发票综合业务的分析决策提供了一种手段。 在阐述地税发票综合业务分析决策系统的解决方案的过程中，本文首先提出该系统设计的总体框架，然后依次分析各个子模块的实现：在数据仓库结构设计中采用了DB-DW-DMs体系结构(独立Data Marts)，数据预处理通过DTS工具完成，对多维数据集的OLAP分析和数据挖掘运用了多维表达式MDX与Microsoft ADO MD数据对象等技术，报表处理与生成通过使用支持PivotTable Service的客户端应用程序Microsoft Excel 2000来实现，数据挖掘模块通过运用DSO编程实现数据挖掘模型的创建和训练，及以可视化的方式展现分析结果等。接着列举实例说明系统功能，最后，总结研究工作并提出下一步工作的方向。更多还原

【Abstract】 With the rapid development in Data Warehouse, OLAP and Data Mining techniques, great progress has been achieved in Decision Support System (DSS). An integrated DSS is mainly based on a Data Warehouse platform, with the use of OLAP and Data Mining tools. DSS is a solution rather than a product. An accepted rule in the realization of DSS is to layout a system structure, implement the system incrementally, benefit from the very beginning, and improve the design over time.hi this thesis, the concepts, implementation and development of Data Warehouse and Data mining are introduced briefly. The focus of the thesis then centers on applying these techniques to the development of an Invoice Integrated Service Analysis and Decision System of Local Tax Bureau. As it is well known, there has been great demand in meeting the new challenges that governmental revenue departments are facing: better client services, strengthened tax administration, improved resource management and the requiremet in evaluating new tax rules and policies. The proposed system utilizes OLAP and Data Mining techniques to analyze data in Invoice Integrated Service Data Warehouse on a multi-dimension and multi-level approach. It provides a solution for local tax bureau management to perform analysis and decision-making about Integrated Service of InvoiceA framework has been built for the solution of Invoice Integrated Service Analysis and Decision System of Local Tax Bureau. Modules within this framework have been generated. The design of the data warehouse uses the DB-BW-DMs (Independent Data Marts) structure. Data pre-processing is dealt with the DTS tools. For OLAP-analyzing and data mining on multidimensional data, the Multidimensional Expressions MDX, and Microsoft ADO MD data object techniques are used. Report processing and generation are realized by using Microsoft Excel 2000, which is one of the client application programs that support PivotTable Service. Data Mining Module realizes creating and training data mining model programmatically by using DSO (Decision Support Object). And results of analysis are showed by visualized mode. Examples have been given through the thesis to demonstrate the concepts and support the design. Conclusions have been provided at the end of the thesis to summarize the current work, and to point out future research directions.更多还原
