针对数字图书馆资源服务系统积累中的大量数字资源访问数据，研究并实现基于数据仓库及OLAP技术的数字资源服务分析系统。首先建立了与资源服务系统分离的数据仓库，并对数据仓库进行多维建模；然后对多维数据模型进行切片、切块、旋转、上钻和下钻等多维操作，从多角度对数字资源访问数据分析；最后采用前端开发工具开发了可视化的多维分析和数据展示平台。实践表明，基于数据仓库的数字资源服务分析可以图书馆管理层提供有效的决策支持。

Based on the large amount history data aeeumulated in the digital resources service system, the digital resources service analysis system based on data warehouse and OLAP technology was studied and implemented. First, the independent data warehouse of the digital resources service was established and the multi - dimensional model was set up to make multi - analysis. And then the multi-analysis analysed such as slice, dice, rotate, roll- up, and drill-down are made in order to analyze the data from multi - dimension. On this basis, the front - end development tool was used to develop the display platform for the data, which could be used for integration of visualization analysis. The experiments showed that file digital resources service analysis system could help the administrators of library to make the efficient decision supports.
