ETL Tools are meant to extract, transform and load the data into Data Warehouse for decision making. Before the evolution of ETL Tools, the above mentioned ETL process was done manually by using SQL code created by programmers. This task was tedious and cumbersome in many cases since it involved many resources, complex coding and more work hours. On top of it, maintaining the code placed a great challenge among the programmers.

These difficulties are eliminated by ETL Tools since they are very powerful and they offer many advantages in all stages of ETL process starting from extraction, data cleansing, data profiling, transformation, debuggging and loading into data warehouse when compared to the old method.

RE: Do we need an ETL tool? When do we go for the tool...

Normally ETL Tool stands for Extraction Transformation Loader

This helps you to extract the data from different ODS/Database

If you have a requirement like this you need to get the ETL tools else you no need any ETL
