Top 15 ETL Tools To Know

ETL Tools

In this article, we are going to learn about ETL( Extract, Transform, Load ) Tools. We will walk you through the following topics: What are ETL Tools, Top ETL Tools, Unique features of each ETL Tools, ETL Tools Categorization whether they are Open Source tools, Enterprise tools, Cloud services, etc. Open source tools, enterprise tools, cloud services, etc., and many more frequently asked questions about ETL Tools like What are famous ETL Tools, Is SQL an ETL Tool, What ETL Tool google uses, etc. At the end of this article, you will have a good understanding of the fundamentals of ETL Tools.

What are ETL Tools?

Before jumping to the definition of ETL Tools let’s understand what does ETL stands for in ETL Tools. So ETL here stands for Extract, Transform, Load. The broad method of copying data from one or more sources into a destination system that depicts the data differently from the sources or in a different context than the source is known as extract, transform, and load (ETL) in computing. Now, let’s understand them one by one. 

Data Extraction 

  • The first step of the ETL process is extraction.
  • In this step, data from various source systems is extracted which can be in various file formats like RDBMS, Excel files, XML files, flat files, Indexed Sequential Access Method (ISAM), etc. 
  • Because the extracted data is in multiple forms and might be corrupted, it is vital to extract data from several sources systems and store it in the staging area before putting it into the data warehouse.
  • Hence loading it directly into the data warehouse may damage it and rollback will be much more difficult.
  • Therefore this is one of the most important steps of the ETL process.

Data Transformation

  • The second step of the ETL process is transformation.
  • In this step, a set of rules or functions are applied to the extracted data to convert it into a single standard format.
  • It may involve following processes or tasks 
  1. Filtering: loading only certain attributes into the data warehouse.
  2. Cleaning: filling up the NULL values with some default values, mapping USA, United States, and America into the USA, etc.
  3. Joining: Joining multiple attributes into one.
  4. Splitting: Splitting a single attribute into multiple attributes.
  5. Sorting: Sorting tuples on the basis of some attribute( Generally key attribute).

Data Loading 

  • The third and final step of the ETL process is loading.
  • In this Step, the transformed data is finally loaded into the data warehouse.
  • Sometimes the data is updated by loading into the data warehouse very frequently and sometimes it’s done after longer but regular intervals.
  • The rate and period of loading solely depend on the requirements and vary from system to system.

All these operations that we mentioned( Data Extraction, data Transform, Data Loading ) are performed by an ETL Tool.
