title: What is the best stream for Big Data
body: <p>I want to do data analysis on my Oracle DB for BI. Now my stream is as follow:<br><br>
  <b>Source DB (Oracle)</b> => <b>Convert to HDFS file by using Sqoop</b> => <b>Use Spark to query on HDFS file</b> => <b>Write out put of Spark as csv File in Hadoop</b> => <b>Use Sqoop to convert to Destination Oracle DB</b> => <b>Present output data</b></p>
  
  <p>Is this an effective approach?<br>
  If not please recommend the most effective approach in very detail</p>
