Extract, transform, and load (ETL) tools allow organizations to extract data from multiple sources, transform the data into a usable state, and load that data into a data warehouse or data lake. From there, the data can be used for all sorts of business purposes, like data analyticsdata visualization or machine learning.

What Is ETL?

ETL — which stands for extract, transform, load — is a data integration process in which data from multiple sources is extracted, transformed into a more usable and consistent state and then loaded into a centralized location, such as a data warehouse or a data lake

Applying a set of business rules, ETL cleans and arranges raw data for easier storage and analysis. This way, teams can quickly process data with machine learning to glean valuable insights for improving workflows, creating reports and performing other data-related tasks.

ETL is typically supervised by data engineers and automated through ETL tools and software. Some data engineering teams choose a full-service ETL product, while others prefer to create their own ETL pipeline using Python, SQL, Apache Spark, Hadoop and Java.

 

Types of ETL Tools

There are four main types of ETL tools for centralizing data under various circumstances.      

 

Enterprise ETL Tools

Enterprise ETL tools cater to larger businesses that have to handle massive amounts of data. While each enterprise ETL tool has its own distinct features, most enterprise ETL tools provide graphical user interfaces for completing tasks, work well with relational databases and can execute complex actions like manipulating data and automating a range of processes.

 

Open-Source ETL Tools

Open-source ETL tools are available to the public for free, and their source code is also publicly available. Open-source ETL tools may vary greatly in their abilities, but many are helpful for data management and data warehousing.

 

Cloud-Based ETL Tools

Cloud-based ETL tools provide a range of services on cloud computing platforms. These tools allow businesses to quickly perform various data-related tasks while charging based on usage, making them a cost-efficient option. But many cloud-based ETL tools have strict proprietary standards, so users can’t transfer their services to another cloud vendor’s platform or to their own platform.

 

Custom ETL Tools

Custom ETL tools are tailored with general-purpose programming languages to meet a company’s unique data and business needs. Teams may use a combination of languages, like Python and SQL, and tools, like Apache Kafka and Hadoop, to create their own data pipelines. While this approach provides a high degree of flexibility, it’s also much more tedious since teams are in charge of their own data maintenance, documentation and ongoing development testing.  

 

16 Top ETL Tools to Know
