Data engineers are IT professionals who primarily prepare data for Operational and Analytical uses. In other words, Data Engineers are responsible for building and maintaining Data Pipelines and Data Warehouses that house Big Data in such a way that allows data to be accessible later on.

Data Engineers work concurrently with Data Architects, who work to manage data systems and understand a company’s data use; Data Scientists, who focus on Machine Learning and Advanced Statistical Modeling; and Data Analysts, who are saddled with the responsibility of interpreting data to develop actionable insights, to develop, test, and maintain Data Management systems, including large scale processing systems and Databases.

Importance of a Certified Data Engineer

The popular buzzword – “Big Data” is not new anymore, you must have heard people talk about it and other keywords like Data Science, Data Engineering, etc. on different occasions. Now, a question comes to mind, Is it really worth it to invest your time in training to be a Certified data Engineer? The answer is YES.

Start with the increasing demand for Data Engineers. For you to be motivated to invest your time and resources in training to be a Certified Data Engineer, there must be a high demand in the industry you are about to venture into. The IT industry is evolving really quickly and the need for Data Engineers is on the rise.

You can have not realized the fact that we all generate data in our world today. Even as we sleep, we all generate data through our mobile phones and computers. So you can imagine the amount of data present in the world as a whole, and the need for more Certified Data Engineers.

Another reason is the fact that data is used in every industry in our world today. This is to let you know that Data Engineers and other data professionals are not limited to just a few industries. Information Technology, Finance, Manufacturing, and Automobiles are some of the prominent industries where Data Engineers are in huge demand.

In the same vein, training to become a Certified Data Engineer is really worth it in the sense that once you are Certified, it provides you a competitive advantage. Data-driven decision-making is a key ability of Certified Data Engineers, and when you make these kinds of decisions, you are purely making decisions based on the analysis of data rather than instinct.

A Certified Data Engineer needs to be on edge with a wide range of technologies and Machine Languages. Also, not only should a Data Engineer be comfortable with a lot of languages, he should be able to deploy each language for specific reasons when the need arises.

However, the following skills are expected as a must in a Certified Data Engineer:

  • Knowledge of Database Architecture and experience in Data Warehousing
  • Knowledge of developing fully functional large-scale applications
  • Proficiency in a wide array of programming languages, especially Python, R, Java, C/C++, MatLab, Ruby Perl, and SAS
  • Proficiency in Operating systems, especially Linux and Unix
  • Database solution languages
  • Splitting Algorithms and Distributed Computing
  • Working knowledge of Regression Analysis and a good grasp of Statistical Modeling

Of course, a Certified Data Engineer must have certain technical capabilities, but the list is not limited to the above skills and much of the job rests on the ability to make Data-driven decisions.
