Abstract: The schema in the Relational Database Management Systems is used because of the unstructured data and the overhead of Extract, Transform and Load. Schema is important in the data analysis particularly in the tools such as Hadoop. Schema enables the loading of raw data and processing and ultimately help to interpret the data. Data sharing is important in the public data store. We in this paper applied the schema on read modelling and it will help to transfer big data and use source data. We conducted a case study in road traffic with the Hadoop Distributed File System, Apache data ware house and the query language.

Keywords: Big Data Analytics, Data Sharing, HDFS, HiveQL Schema Application of the Read Modelling using Hadoop
