Abstract: The grain forecast system based on data warehouse is designed and realized. Taking advantage of data warehouse, the forecast subjects can be controlled easily and several forecast methods can be selected using the method of layer structure of forecast subject and multidimensional data model of forecast instance. Contrast to the professional and complex system,the aim of understandability and easy-operation is realized.This system has been used in IDSS of grain and has been of some values for decision support.
