Extract, transform and load (ETL) is a form of data integration. It includes the processes that pulls the data from the OLTP database and loads the OLAP database. The importance of ETL is revealed in the fact that, many companies today that are operating on the cloud are actually using Hadoop to offload their ETL processes from traditional platforms to a more scalable platform such as Hadoop.
Things are extremely simplified. Here, you can write your ETL logic once and to deal with more data, you need to add more nodes to your Hadoop cluster. Significantly, ETL or extract, transform, and load processes serve as the backbone for enterprise data warehous
