Data Scientist vs. Data Engineer

The field of Data Science continues to evolve every day with newer and prevalent roles like that of data scientists, data analysts, engineers, and data architects becoming restructured and more essential to every industry. Big Data has changed how organizations deal with their problems, making their path of success dependent more on facts than chance. Yet, due to this ever-evolving nature of the world of Data Science, the concept and workings remain unclear to many, leading to errors in the process. If you too would like to enlighten yourself and learn more about Data Science and two of the most essential roles that it has given to the world’s businesses and organizations, let’s dive in further.

What is Data Science?

Data Science is an interdisciplinary field of study which uses methods, algorithms, statistics, and more to derive information and actionable knowledge from a vast world of unstructured prevalent data. Today in the modern world, Data Science applies everywhere from Governments to Financial organizations to consumer-oriented businesses. By using already available data and the right methods, companies can prepare for upcoming business opportunities as well as prepare for oncoming disasters. Data Science can be and is utilized from the most minor to major face-alternating organizational concerns.

Now that we know what the field of Data Science is, let’s take up the essential professional roles that are responsible for executing the theoretical knowledge of Data Science into real-world applications – Data Scientists and Engineers.

Who is a Data Scientist?

Harvard University in a report had ranked the profession of a Data Scientist as one of the most inviting jobs, and we agree. But what is the job of a Data Scientist? They are deemed analytical experts who work on all kinds of structured and unstructured data, study it and model it as they deem fit, and finally analyze it to create executable plans for the company’s future.

To become a Data Scientist, you need to be knowledgeable on many grounds as has been discussed below.

Technical and Soft Skills Required to be a Data Scientist

  • A Data Scientist needs to be well-oriented with at least one programming language if not more. These may be Python, R, C++, Julia, etc.
  • Data Analysis with platforms such as Excel, SQL, Pandas, etc.
  • Heavy Knowledge of Statistics and probability is a must without which machine learning will be impossible.
  • Strong mathematical skills.
  • Needs to know how to use Data Visualization tools such as Tableau.
  • Moderate knowledge of machine learning methods and AI.
  • Data Modeling must be in a Data Scientist’s forte. The popular choice for which is the Hadoop platform.
  • A Data Scientist must be a good communicator to convey their findings to the stakeholders.
  • A Data Scientist must be a curious and critical thinker so that they can think ‘out of the box to provide necessary solutions.
  • A Data Scientist must be a clear storyteller in order to be transparent in conveying solutions and collaborating with teams.

Who is a Data Engineer?

A Data Engineer is responsible for providing the data that Data Scientists can work on. They collect raw data from everywhere, manage it and convert it to usable data that can be studied by analysts, scientists, and so on. They are the Data Handlers of an organization.

Like a Data Scientist, a Data Engineer needs to be skilled on many grounds.

Technical and Soft Skills Required to be a Data Engineer 

  • Acquaintance with coding languages like SQL, Python, Java, Scala, and so on.
  • They must be well oriented with the Extract, Transform and Load System. Popular tools include Talend, Xplenty, Stitch, Alooma, etc.
  • Data Engineers must know about popular Warehousing Solutions and also be aware of relational and non-relational databases for storage.
  • A Data Engineer needs to be familiar with the concept and systems of Machine Learning.
  • Be able in Task Automation.
  • Have a solid grip on cloud computing.
  • Along with Data engineering, comes the need for the ability to keep the data secure and protected.
  • Know about big data and should be able to use big data tools like MongoDB, Kafka, Hadoop, etc.
  • Data Engineers need to be good collaborators and communicators to work fluently with working teams, analysts, and business units, and so on, especially to source data.
  • A Data Engineer may be required to perform data analysis and present results to stakeholders. Thus they must have excellent presentation skills.
