For example, the marketing ETL process, where tons of data is collected or extracted using the process of marketing data integration for the purpose of creating campaigns. There are multiple examples that you can think of under this process. Now, there are multiple instances where the data extracted may be corrupted and can ruin the entire structure of the Warehouse if not monitored. The staging area is the platform where the data is sorted out before sending it directly to the Data warehouse. In this first step, data is extracted from various sources and all the different formats and collected in the staging area. The steps are Data Extraction, Data Transformation, and Data Loading. The ETL process : A deep diveĪs we discussed, ETL is a three-step process to carry out the process of data integration from source to destination. However, setting up ETL systems and pipelines is not a simple task due to the inherent challenges of handling multiple data sources each with their own APIs, authentication systems, data formats, rate limitations etc coupled with continually changing business requirements and needs.

The industry tends to label the series of steps in ETL as setting up an ETL pipeline analogous to an actual pipeline. The ETL process requires active inputs from various stakeholders, including developers, analysts, testers, top executives, and is technically challenging. The data is foremost extracted from the sources available, and this data is then transformed into the desired format and then loaded to the Warehouse for further analysis. It is an acronym for Extract, Transform, and Load. That meant they were spending only 22% of their time on more value-adding tasks such as data innovation and the extraction of valuable insights.”ĮTL refers to the process of transferring data from source to destination warehouse. According to a Gartner report : “Data professionals on average were spending a whopping 78% of their working time on routine data management work and support. In short, what started out as the panacea for more informed and better business decision making becomes an annoying bane. They soon result in sluggish data silos, impeding access and data visibility across functions adversely impacting the businesses. These data stores become increasingly complex and massive as companies scale and grow fast. Each of these sets of tools and applications have created their own ecosystems with prodigious amounts of data.
The rapid shift to cloud native technologies has provided a number of opportunities to even relatively small businesses to use a number of SaaS tools and applications at nominal prices. Every business with any hopes of growth is adopting data driven decision making and the modern data stack sits at the heart of this irreversible change. Recent pandemic further accelerated this already exponential growth with no stopping on the horizon. Modern information technology has permeated every facet of this digitally connected world. The explosion of data in every aspect of our lives is now a fact.
