多层DSS体系结构研究

Study of Multi-Tiered DSS Architecture

在设计和部署DSS时,由于对DSS体系结构认识不清,常常不能做出正确的选择.而对DSS体系结构的正确选择正是成功实施DSS的关键.详细地分析了第一、二代DSS模型在具体实施和运行过程中存在的问题,提出了一种综合的多层DSS模型,并设计了软件体系结构.该模型综合了数据仓库和数据集市的优点,解决了第一、二代DSS模型存在的不足,对规划和部署DSS具有一定的指导意义.

In designing and deploying DSS, usually, we do not know what to do, because of not knowing DSS architecture. Choosing right DSS architectures is the key of success. In this paper, analyzes problems existed in implementing and operating the first and the second generation of DSS models,puts forward an integrated multi-tiered DSS model, and designs architecture of the software. The model integrated the advantages of data warehouse and data marts and solved the problems of the first and the second genefation of DSS models. With its guidance, we can well deploy DSS.
