There are many caveats to becoming a Data Engineer, and the journey isn’t exactly easy. However, the dedication and hard work invested into becoming a professional in this field are well worth it once you achieve success. Data engineers are crucial in ensuring that data is efficiently transformed for analysis and dissection into different vital elements for a specific project.
We all know you’re here solely to understand what skills are required to become Data Engineers. But first, you should also know one of the programming languages for Data Engineers.
Indeed, data engineers’ role isn’t tied to one set of skills but a broad and encompassing responsibility that supports data science technology as a whole. Data engineers are only as sound as the data they can access, which is why they focus mainly on the most complicated volumes of data, as their success can add incredible market value to any business.
Data engineers are responsible for creating algorithms and discovering patterns within data sets to develop opportunities for raw data to become more valuable. It may sound easy, but such a role requires expertise in various technical skills and knowledge of different programming languages. Here is a compilation of some of the best digital languages used in programming by data engineers to put that into perspective.
Best Programming Languages for Data Engineers
Here we’ve listed the most preferred programming languages used to become Data Engineers.
Python for Data Engineer
One of the most apparent inclusions is Python, as it is terrific for new data engineers to learn because of its capabilities. It is also one of the easiest programming languages to learn. Python isn’t only reserved for data applications but a plethora of other usage scenarios as well. Engineers can code a program for different operations in machine learning, deep learning, and other AI-based systems.
Python has been constantly updated with new features and technology over the years and is one of the leading programming languages used by professionals worldwide. The sheer number of tasks that Python can consistently solve makes it worthy of taking a spot on this list.
It’s estimated that most of the lists you see online about programming languages for data engineers unanimously mention that Python is the most popular. Taking a look at some of these advantages and disadvantages can give you a clear picture of why that has been the case for many years. It’s not that hard to determine what languages data engineers use daily, since the statistics show precisely what programs are being commissioned regularly in companies.
- Modularity and specific libraries can be added at any time to mitigate any problems.
- The additional tools are necessary for most functions are offered in the public domain.
- Python allows users to start a project from scratch, ranging from simple to complex AI-learning programs.
- Python’s interface is simple, intuitive, and beginner-friendly.
- Years of experience in technical and customer support are waiting to assist you should there be any program problems.
- Some errors may occur in specific dynamic typing scenarios, which results in the wrong distribution of essential data to variables of equal value.
While Python is the best programming language for data engineers, it is difficult to say it is, without a doubt, one of the most popular programs as of today. Time will tell if new programming languages will surface to compete with Python, but the likelihood of this happening is rare.
R for Data Engineer
Another one of the leading programming languages in data science is R, which is also invaluable in serving as a statistical analysis tool for existing languages. R’s ecosystem can’t be described only as a language but a whole unit of calculations in statistics for important data sets. The program allows its users to perform modeling, algorithm building, data processing, and graphical fidelity work.
R has been in the market for years and is currently being used by 70% of data miners in the world today. As a result of R’s technology and reliability as a programming language, over two million concurrent users worldwide remain faithful to its functions and features.
R is also used in Data Science.
- Anyone with a background or interest in statistics will feel right at home using R as the nature of its technology revolves around statistics. Visualization of any information and data is seamless with its intuitive interface.
- Cross-platform and open-source features allow R to operate on most systems giving it the flexibility advantage over other programming languages.
- Speed, memory bandwidth, and safety are some of the concerns users have reported while using R.
Some of the popular use-case scenarios that R has seen are detection systems in credit card fraud, email fraud, and various other platforms. Using an R-based analysis model to perceive what users think of a product is also quite helpful when applying the technology to artificial intelligence systems.
Many people also don’t realize that R and Python can be combined in a project to take advantage of both their features. Connecting these two leading language programs allows for a unique and extensive set of functions and features.
SQL for Data Engineer
The capabilities of structured query language alone make it one of the top choices for operations performed on vast data volumes. This is because SQL is capable of complicated analytical procedures and transactional analysis of different data sets. It may vary between company requirements, but most data engineers must have ample knowledge of SQL and its functions.
- SQL as a programming language is standardized worldwide, making it familiar in any field of data science.
- Programming languages are usually complicated and require a lot of time to master, but SQL is simple, flexible, and allows for flawless transition between technologies if needed.
- Most data science schedules follow a strict workflow and SQL lives up to that standard by complying with a consistent timeframe.
- Direct access to data sets gives SQL the ability to operate at high speeds.
- Sometimes data engineers would find that SQL’s analytical functions fall short in comparison to other programming languages. Some of these limitations lie in aggregation, counting, summing, and calculating the averages of data.
Data engineers would often place SQL’s strength as a programming language to manage data for online and offline applications. Therefore, it is crucial to know the specific needs of a project before adding SQL to the list of programming languages.
Summary: Programming Languages for Data Engineers
These three are the best programming languages for Data Engineers, learning any one of them will help you to become a future data engineer.
If you’re someone who’s starting and trying to figure out what languages do data engineers use regularly, then the programs in this article are a great start to that journey. It might take some time to learn each language’s capabilities and functions, but meaningful knowledge takes time, and every aspiring engineer in the field of data science keeps that at heart.
