摘要
在对关系数据库业务模型分析的基础上通过建立多维模型定义使数据具有多维的概念,并在此基础上提供了一种B/S模式的多维数据查询和展现的方法,该方法充分利用了多种数据存储结构来优化数据的查询和显示。通过建立维度间的层次关系可实现多维数据的钻取、旋转、切片等操作,结合JFreeChart的图形功能提供了一种多维图形展现和分析的方法。
On the basis of business model analysis in relational database, by building multidimensional model definition make data having the concept of multi-dimension. And a method for multidimensional data query and presentation in B/S mode is provided based on the multidimensional model definition. This method takes full advantage of many data store structure to optimize data query and display. Bybuilding different levels of dimensions implements the multidimensional data operations of drill, pivot and slice. Combining the graph of JFreeChart provide a method of multidimensional picture presentation and analysis.
