Research on framework for urban railway massive data based on cloud computing platform

It´s important to effectively storage, computing and translate the massive data (i.e. passenger flow data, equipment monitoring data) into information. This paper proposed a data processing framework based on cloud computing for urban railway. First of all, the existing problem of traditional data processing platform for urban railway was analyzed; Then, the advantages of cloud computing platform was presented, the merits and faults of the current main cloud computing products was compared; Finally, an urban railway data processing framework based on cloud computing was proposed. This framework was based on Hadoop, used the HDFS to storage data, employed the MapReduce to calculate data and invoked the Hive to mine the data. This paper laid a good foundation for introducing cloud computing to urban railway as its information platform.
