A Multidimensional Pivot Table Model Based on MVVM Pattern for Rich Internet Application

Data warehouse and OLAP provide a powerful support for decision support system. As an effective means of multidimensional data visualization, Pivot table has been widely applied. However, most of the existing multidimensional data exhibition systems based on web mostly have the features of weak interaction, difficult customization and maintenance, poor performance of updating the table structure or submitting and querying repeatedly, as well as not taking full advantage of the client computing resources. In order to solve these problems, this paper proposes a multidimensional Pivot table model based on MVVM pattern, discusses the structures and characteristics of the model, and finally effectively deals with the data exhibition problems for APQSEWS based on the rich Internet application. The model independent of specific platforms is proved strong flexibility, efficiency and scalability.
