Amazing ETL tools are Informatica, Talend, Pentaho.
The backbone of ETL is Structured Query Language or SQL as it is the most popular database language. Every part of ETL can be done using SQL. There are a lot of Programming Languages which people use, but the most reliable one is SQL.
Mostly the ETL tools are just the SQL generators behind the back, so it becomes crucial to use both interchangeably.
Learn the skill of parameterizing your ETL jobs, which will initial save a lot of time. Using the parameters will make you dynamically change the aspects towards the ETL jobs.

While the ETL developers must be ready to take a bigger view of the company’s data situation. It is a type of skill set that most of the people look at data modeling.
The ETL developers should have the ability to read, analyze and transform the data what the company wants to do with it. Then design the best possible ETL designs to process it through the goal.
The ETL Job roles require someone with more in-depth knowledge of the different programming languages. With excellent communication skills combined with the best analytical mind.

This even includes the verification of data at various stages that use between the source and destination.
There are five stages in ETL testing that are:
- Recognizing Data sources and specifications.
- Data acquisition
- Executing business logics and dimensional modeling.
- Building and populating the data
- Making reports
