A Datawarehouse Model Supported Product Development
Yongqing Zheng · Acta Simulata Systematica Sinica · 2002
Today most datawarehouse systems use the Snow-flake model as their data model, but this model has some disadvantages including its dissatisfied access efficiency. Our datawarehouse system is used to support product development decision-making according to the product抯 sales in market, and the Snow-flake model can hardly satisfy our demands. In this paper some ideas of object oriented technic are combined in customary snow-flake model, and the result of which is a new mixed datawarehouse model of both object oriented technic and snow-flake model. The outstanding access capability of the new model is also validated with experimental data.
