What is Best for You: Data Science or Data Engineering?
Data scientists and data engineers are similar yet vastly different from one another. If you are still confused about what you should choose, we have a little treat for you.
If your jam is working on cluttered data and using scientific methods and algorithms to derive insights, data science could be for you. Not only that, you would be able to work with businesses and help them grow their company.
That is not all.
You can work in healthcare, construction, retail, banking, and many more! The key factor being you have what it takes to identify problems by evaluating data and finding methods to solve them as well.
However, if you want to go a step further and design systems that facilitate data collection and storage, you would be better off as a data engineer.
Data engineering is not one of the fastest-growing jobs for no reason.
Jonathan Coveney, data engineer at Stripe says "There's a growing sense today that data isn't just a byproduct, but rather it's a core part of what a company does". No truer words.
Data engineers build the very foundation of systems that data scientists work on, as they have a deeper understanding of data architecture and manipulating that data. As a data engineer, you will be able to explore this field at the start of its boom.
Before we rank scores, let's establish that one is not better off than the other. Both are equally important in any organization, and it's their combined effort that brings the magic to the table.
How do you get started on either of these careers?
Data Engineer vs Data Scientist: Educational Background
A computer science degree can get you both places if you're still unsure. However, if you do not want that, you could do a degree in mathematics or statistics. Data science is a lot about extracting value out of data sets, and so a mathematical brain would be stellar on the role.
Data engineers also come from other backgrounds, but they usually come with a degree in computer science engineering.
Data Science vs Data Engineering Certifications
If you want to shift careers or are hesitant to commit to a degree, you can take certifications in data science and data engineering. As long as you build your skill, recruiters will be obliged to recruit you.

Which Field is Better: Data Engineering vs Data Science
There are pros and cons to both fields, as they are still in the developmental phases. The responsibilities are not cut differently yet, and there might be a lot more mixed duties than what was accounted for.
Can data scientists work as data engineers?
In the current scenario, yes!
Data scientists are trained to manage big data and derive solutions, which will cover the basic tasks of a data engineer as well.
As a data engineer, you will also be able to join as a data scientist because you will be familiar with the concepts that they deal with.
However, if you made a career switch and say you have a degree in an unrelated field, you would have to take additional courses to be on par with the knowledge of other data engineers.
Since data scientists do not have to be technologically sound, the number of tasks will be vast and limited at the same time. In this situation, data engineers are more desirable as they can perform optimally with the tasks they are given.
You can always test the fields before you make a commitment, but these two factors may give you a bit more insight:
- Study shows that there are five times more job openings for data engineers than for data scientists
- Data scientists try to find better job opportunities and are less likely to stick to their career
The only thing left to do here is taking a long and analytical look at your skills, interests, and general facts about both fields. With the right pros and cons list, you will be able to make your decision in no time!
Due to the nature of their work, data scientists and data engineers do different tasks to achieve the same goal. However, instead of choosing one over the other, companies keep a healthy mix of the two to reap maximum benefits out of the power duo.
Here is what you now know:
- Data engineers prepare data for analytics, while data scientists perform statistical analyses of raw data to extract useful patterns
- While the average salary of a data scientist is $117,080, data engineers earn a yearly average of $116,744 because of their difference in demand
- Data scientists show familiarity with tools like MatLab, Hadoop, and programming languages like Python and R, while data engineers are acquainted with tools like SQL, ETL, AWS, etc.
- Both data scientists and data engineers have a degree in computer science, but data scientists can work with a degree in statistics, mathematics, etc., as well
