ETL (extract, transform, load) is a type of data integration process of moving raw data from multiple sources and loading it into a centralized data warehouse. This is a vital component in making the data analysis ready to have a smooth business intelligence system in place. It improves data professional’s productivity and makes it easier for business users to analyze and report on data relevant to their initiatives. ETL applications handle mobile and Web data very efficiently and be a part of large industry standards and norms.

ETL tools are applications/platforms that enable users to execute ETL processes. In simple terms, these tools help businesses move data from one or many different data sources to a destination. This helps make the data both digestible and accessible in the desired location – often a data warehouse. Deciding an ETL tool is hard work for companies as these tools automate most of the workflows without requiring human intervention, but if not careful, it can also become a large money pit.

Some of the best ETL tools in the market are Improvado, Xplenty, AWS Glue, Parabola, Alooma, Apache Nifi, StarFish, Clover DX, Pentaho DI, Jasper, Talend Open Studio, Informatica Power Center, Stitch, and Oracle Data Integrator. Informatica can publish the database process as web services, conveniently, easily, and speedily. Informatica helps to balance the load between the database box & ETL server, with coding capability. Astera Centerprise is the most accessible tool to learn for DI jobs.

How to Create Your ETL for Business Intelligence Strategy:

Before an organization adopts ETL for business intelligence strategy, there is a lot of groundwork and components necessary to accelerate a business push.

Analytics needs to be chalked out:

Keeping a track on the historical data like sales, profit margins, return on investment, your valuable client needs, helps to develop a firm understanding of all the benchmarks set by the company and configures your ETL to fit your company’s specific BI needs.

Sourced Data:

Most businesses have data from different sources like Core Data via mobile app, website, online shopping, etc. Peripheral Data via customer relationship management services, External Data via data from sentiment analysis. Figuring out which data is most relevant from each source and having a comprehensive look at it.

Data Warehouse:

Once the data is sourced, choosing and building a data warehouse while keeping in mind some important things like scheme design, Cloud vs. On-Premise, DB size, Concurrency, Scaling can go a long way in building your business strategy.

Strong BI Team:

The head of the team should be equipped with good technical skills to improve your business, a good BI developer to design and integrate information extracted and loaded into the data warehouse, A Database Analyst creates new applications, manages an organization’s metadata thereby transforming the analysis into actionable insights.

Trends that will define the future of ETL

The advances in data processing have laid the foundation for the shift towards cloud-storage and the arrival of Big Data. ETL processes are handling vast amounts of data at incredible speeds; Google Fibre now boasts a connection speed of one gigabit per second. SA unified data management system combines the best of data warehouses, lakes, and streaming without expensive and error-prone ETL. It utilizes a single storage back-end with benefits of multiple storage systems and thus avoids duplication and data consistency issues.

Databricks Delta is a perfect example of this. Both Alluxio and Apache Arrow (common In-Memory Data Interfaces) which supports zero-copy reads for lightning-fast data access without any CPU overhead. Dealers are already applying hardware advances such as graphics processing units, Tensor units, and single instruction multiple data to create solutions up to 100 times faster than a traditional data warehouse. These are current machine learning trends with a 70% speed and can exploit modern processor architectures that achieve six times improvement over warehouses.

Data Virtualisation V/S ETL:

Data virtualization is the sole interface that processes data that originates from different sources and applications. It can aggregate and efficiently bridge data across warehouses, data lakes, without having to create a whole new integrated physical data platform. This technology can perform all the core functions of data integration, which complements all existing sources of data, thereby increasing the usage of enterprise data. This technology has gained popularity and can be considered as an alternative to ETL. It aims at providing quick and timely insights, whereas the latter is often slow, complicated, expensive, and may result in some loss of information.


Companies need to invest in such ETL marketing tools to gain an advantage over their competitors by taking into account their own goals, corporate objectives, and needs. This technology can make a substantial impact on our business if the deployment of the best ETL marketing tool is made after a thorough decision-making process.
Server-less computing is a distinct shift in application development. It enables developers to focus on writing codes without the hassles of infrastructure that is zero server management, no up-front provisioning, auto-scaling, and paying for services used. Companies that adopt theseRead More
