Abstract:

Based on the characteristics of big data,the paper proposes quickly recognizing top search queries by the tag cloud.It also introduces the advantages of the traditional data warehouse in query and storage structure,and puts forward a different method of data transfer from the traditional ones in the collaboration mode,which is based on the combination of data warehouse and Hadoop platform.The data middle ware is used,and a comparison between the time taken for the same quantity of records to be introduced into Hadoop shows that the method proposed is superior to Sqoop.
