摘要:According to the current development of cloud computing and limitations of data warehousing and data mining technology, we proposed The intelligent decision supporting technology of cloud-based public data warehouse and gave the principle of the technology, the implementation process, and constraints the key issues of development prospects. The study of this technology can be realized solution of knowledge discovery in many fields of research within the global. The knowledge it produces can not realized by any other technical so far. It will be direction of development of data mining technology in the future.
