This article is for you if you considering to use Data Warehouse Automation (DWA) and asking yourself what DWA tools should do for you. After I explain in my previous blog Why Data Warehouse Automation is not more popular, you will find the why and what of DWA in this second post of the series.
Every industry has used automation to increase productivity, reduce manual effort, improve quality and consistency, and speed delivery. Henry Ford introduced the assembly to produce automobiles, and today Uber and countless other startups use the Internet and digital processing to reduce friction in commercial transactions. Thus, the time has come to introduce automation to data warehousing.

I would say it like this. In a society where time flys remarkably fast and data became the new gold, it’s crucial to have proper analyses or even data predictive trends to navigate the company in the best direction. In order to get there, I believe automation is needed more than ever before. It’s not the time to do recurring tasks manually over again and producing additional errors. DWA could deliver you the first KPI‘s within weeks based on your data foundation you already have. Why then waste another month, or two to figure out technical details instead of focusing on analysing the data and the business requirements?
Some key reason why I would want to automate:
Now we know why we want to automate, but what is it actually that DWA is doing? Mainly the following:
But probably the most important point here to highlight is repetition. We do the same thing over and over again in Data Warehousing. Is it adding staging tables or to any layer, changing the structure of an attribute, creating schema (star, snowflake, third normal form, or data vault), adding foreign keys to the fact tables, creating the view layers, adding slowly changing dimension, create default indexes, …, the list goes on and on.
It is actually hard to find a reason not to automate. As highlighted firmly above it improves quality, increased agility, provides you with the ability to iterate fast and reduces cost with better sustainability, maintainability and operability. At the end of the day, you cut development time and effort to reduce project costs and increase return on investment. Don’t waste more time and work smart at the speed of business with DWA!
