文章通过对基于数据库的知识发现系统(KDD)的研究,提出了双库协同机制,它改变了KDD的结构、运行过程与机制,形成新的知识发现系统KDD。将该发现系统应用于农业领域,为合理地指导农业生产提供了科学的决策,因而具有重要的理论意义和实用价值。 Through the research of database-based knowledge discovery system (KDD), this paper proposes a double repository synergy mechanism, which changes the structure, operation process and mechanism of KDD and forms a new knowledge discovery system KDD. Applying the discovery system to agriculture and providing scientific decision-making for the reasonable guidance of agricultural production have important theoretical and practical values.
