The method of real estate information service based on Hadoop
Houdong Hui Yu Mingyuan Yele Liang Ronghua
Aiming at the problem of operation efficiency of large data information service, this paper proposes a real estate information service method based on Hadoop, and designs and realizes a real estate information service prototype system. Use Hadoop to build a distributed file system that uses Rcfile to store and manage data. In addition, the system integrates data indexing and data compression techniques, and proposes a SQL efficient query mechanism ——— SQL-JM, which transforms SQL query into MapReduce job and improves query efficiency. The front-end uses some information visualization technology, such as Treemap,stream graph, line chart and so on to show the data visually. Users login to the system through the browser, you can apply for and use the relevant real estate information services. The query comparison experiment of HIVE,HADOOPDB,MYSQL database system verifies that the system can improve query efficiency.
