What is ETL? Top ETL Tools

Extract, Transform, and Load are referred to as ETL. ETL is the process of gathering data from numerous sources, standardizing it, and then transferring it to a central database, data lake, data warehouse, or data store for additional analysis.

The ETL process transforms structured or unstructured data from numerous sources into a simple format for your employees to understand and use regularly. Involved in each step of the end-to-end ETL process are:

1. Data extraction

Data that has been extracted has been retrieved from one or more sources, both structured and unstructured. These sources include websites, mobile apps, CRM platforms, on-premises databases, legacy data systems, analytics tools, and SaaS platforms. The data loads into a staging area after retrieval is finished and is ready for a transformation.

2. Data transformation

The transform stage prepares the extracted data for storage on the database, data store, data warehouse, or data lake of your choice by cleaning and formatting it. The objective is to get the data ready for querying in the target storage.

3. Load

Moving prepared data into a target database, data mart, data hub, warehouse, or data lake is known as loading. Data can be loaded in two ways: gradually (incremental loading) or all at once (total loading). The data can also be scheduled to load in batches or loaded in real time.

Incremental data loading eliminates duplication by comparing incoming data to existing data. Every item that exits the transformation assembly line is transported to the final warehouse or repository during a total loading.

What Do ETL Tools Do?

The entire ETL procedure is automated using an ETL tool. ETL solutions employ several data management strategies to automate the extraction, transformation, and loading (ETL) process, reducing errors and speeding up data integration.

And there’s more. Use cases for ETL tools include:

  • Automate the processing, management, and intake of enormous amounts of structured and unstructured data locally and on the cloud.
  • Securely deliver data to an appropriate analytics location.
  • Placing them in a historical perspective may make assessing, evaluating, and comprehending current and historical datasets simpler.
  • Replicate databases to a cloud data warehouse from sources like MongoDB, Cloud SQL for MySQL, Oracle, Microsoft SQL Server, and AWS RedShift. ETL tools can be used to update your data periodically or continuously.
  • Your on-site data, applications, and workflows should be moved to the cloud.
  • Transfer data from numerous IoT devices to a single location so you may further examine it.
  • For a more thorough analysis, combine data from social networks, online analytics, and customer service in one location.
