ETL Testing Training FAQ'S

What is ETL? Explain it.

ETL stands for Extraction, Transformation, and Loading. It is an essential concept in Data Warehousing systems. There are three basic steps in Data Integration Process. Extraction stands for extracting the data from different data sources such as transactional systems or applications. Transformation stands to apply the conversion rules on data so that it becomes suitable for analytical reporting. Loading process involves, moving the data into the target system, i.e., Data Warehouse.

Explain the concept of Extraction, Transformation, and Loading?


Extracted the data from an external source and move it to the data Warehouse pre-processor database.


Transform data task allows point-to-point generating, modifying, and transforming the data.


In this task, the data is added to the database table in a warehouse.

What is the three-layer architecture of an ETL cycle?

The three layers in the ETL are:

  • Staging Layer: Staging layer is used to store the data which is extracted from the different data source systems.
  • Data Integration Layer: Integration layer transforms the data from the staging layer and moves the data to a database. In the database, the data is arranged into hierarchical groups, which is often called dimension, and into facts and aggregation facts. The combination of facts and dimension table in a data warehouse system is called a schema.
  • Access Layer: Access layer is used by the end-users to retrieve the data for analytical reporting.

What is BI?

Business Intelligence is the process for collecting raw business data and transforming it into a meaningful vision that is more useful for business.

What are the ETL tools available in the market?

The popular ETL tools available in the market are:

  • IBM- Websphere DataStage
  • Informatica- Power Center
  • SAP- Business objects data service BODS
  • SAS - Data Integration Studio
  • Oracle- Warehouse Builder
  • Open source Clover ETL.

Not recommended as there will be no server access working to do practical after training. Also there will be no fix for the same. So it's wastage of money. If server access not at all working then no meaning to provide server access. Also it not working for single day properly. Need to followup daily but in response you told will fix that sir at home once he will back will fix. After he came back again it's not working and not able to fix for single day also Every time new excuse it's wastage of money.

I have undergone Oracle Tuning training. I can proudly say that this is one of the best training institutes available in the market. The way Mr. Kumar teaches the concepts and makes them understandable is very commendable and unique. Even a novice can clearly understand the concepts clearly after attending his classes.
