在研究数据仓库的特点、组成及其实现的基础上,对数据仓库和联机分析处理技术进行了研究,构建了一种基于数据仓库的货物进出口决策支持系统结构。解决了数据仓库模型的创建、数据的增量更新及数据分析与展现问题。最后,对基于数据仓库的货物进出口决策支持系统的实现问题进行了探讨。
The detailed research based on studying the characteristics, structure and its realization of data warehouse are made, the technologies of data warehouse, online analytical processing (OLAP) are investigated, and a structure of ware imports and exports DSS based on data warehouse is proposed. Specially, the problems of data warehouse model, incremental processing of data warehouse, and analyzing and exhibiting of data are solved. Lastly, the implementation problem of the proposed system is discussed.
