What Exactly is ETL and Where it is used?

You’ve undoubtedly heard the word “ETL” about data, data warehousing, and analytics if you’re reading this. If you wish to combine data from many sources into a single database, you must first:


the data is extracted from its source, which might be a database or an application.


data by cleaning, deduplicating, consolidating, and generally preparing it for.


The process of moving data from one repository to another is known as data migration.

Typically, one ETL solution handles all three processes, and it’s an important component of ensuring that data needed for reporting, analytics, and, more recently, machine learning and artificial intelligence, is comprehensive and useable. However, the nature of ETL, the data it processes, and where it takes place have all changed dramatically in the last decade, making the correct ETL software more important than ever.

A Brief History of ETL

The emergence of centralized data stores in the 1970s gave birth to ETL. But it wasn’t until the late 1980s and early 1990s, when data warehouses became popular, that purpose-built tools to assist with data loading into these new warehouses were available. The original ETL tools were crude, but they served their purpose. Granted, by today’s standards, the quantity of data they processed was insignificant.

Data warehouses expanded in size as the amount of data rose, and ETL software tools multiplied and got more complex. However, until the late twentieth century, data storage and transformation were mostly done in on-premises data warehouses. But then something happened that forever changed the way we thought about data storage and processing.

How ETL is applied?


ETL tools may assist with a wide range of data management activities and are used by Top ETL companies in India, and are frequently used in conjunction with other tools and technologies.


ETL solutions, at their most basic level, assist organizations in combining structured and unstructured data obtained from source systems and storing it in a data warehouse. Raw data is frequently transformed into table formats that are optimal for reporting, allowing previously hidden insights to be revealed using analytics or visualization tools. Best Top ETL companies in India, for example, may merge name, location, and pricing data from company operations with transactional data coming in, such as retail sales, banking deposits and withdrawals, healthcare claims, and so on. 


Traditional operational and transactional data just touches the surface of the information collected by most businesses today. The quantity of Big Data streaming into businesses via IoT, social media, video, log mining, and other sources is startling. Businesses, on the other hand, use this breadth of data to gain a competitive advantage, comprehend context, and make appropriate judgments.


Conventional data warehouses, structured master data, and traditional ETL methods are being phased out. Many people, for example, use Hadoop to load and transform their structured and unstructured data, and they’re increasingly doing it on the cloud. Data engineers can improve the speed and scalability of their ETL operations by using Hadoop. Traditional data warehousing scales significantly more slowly than a centralized Hadoop repository. Hadoop is also open-source and considered a low-cost alternative to traditional data technologies by many. Therefore, click here to consult with the best ETL company in India.
