摘要

In this paper, we mainly analyze the generic knowledge of report system model which provides the decision support to information systems. We propose an ontology-based report system model which has flexibility and can be used to different kinds of information systems. The paper details the formal description of report ontology, and proposes the composition algorithm which bases on the report ontology. At last we give an application instance which uses this model, the practice proves that the report system model can enhance the development efficiency and reduce the costs.
