About Course

Our ETL Testing Course is an Extract, Transform, and Load (ETL) integration process that combines data from several platforms into a single data storage unit that can then be loaded in data warehouses. The “Extraction of data from different applications” that is created & maintained by separate vendors, managed & controlled by different people, and hosted on different technologies, is what ETL essentially refers to. We cover all the essential ETL principles in our thorough training, including joining and deduplicating data, filtering and sorting data based on certain properties, transposing data, performing business calculations, etc. Enrol today to earn your certification.

ETL Testing Training FAQ'S

What is ETL? Explain it.

Extraction, Transformation, and Loading are referred to as ETL. In Data Warehousing systems, it is a crucial idea. The Data Integration Process consists of three fundamental components. Extraction refers to the process of removing data from various data sources, such as applications or transactional systems. Data is transformed when conversion rules are applied to make it appropriate for analytical reporting. Moving the data into the target system, or Data Warehouse, is part of the loading process.

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.
