In the modern, digital world, every business or organisation now relies heavily on data. Data has become a crucial aspect for the success of any business and is continuously growing with each passing day. As a result, the data market is on the rise and the influx of large amounts of unstructured and raw data created a stark increase in demand for data engineers.

Data engineers are key to building data pipelines and are essential for making data more useful to companies. To build such complex data infrastructure, data engineers need a mix of programming languages, data management tools and much more. Here, we discuss the three essential data engineering tools every engineer should know.


Python is one of the most popular programming languages in the industry and is an essential tool for all data engineers.

Python has gained its popularity as it is easy to learn, and its extreme versatility is a powerful attribute that makes it a key tool for data engineers. It’s multi-use function means that data models can be created, data sets can be systematised, and ML-powered algorithms can be developed; as well as having the ability to complete various tasks in a short amount of time. The key benefit of Python is that it helps to reduce development time, which results in fewer expenses and faster results for companies.

When it comes to the cloud, Python is a popular choice for cloud platform providers for implementing and controlling their services. Some of the biggest cloud platforms, namely Amazon Web Services (AWS) and Microsoft Azure, all accommodate Python users.

Regardless of what sector a data engineer forges their career in, they’re almost certain to encounter Python along the way.


MongoDB is a key tool for any data engineer as it’s easy-to-use, highly flexible, and can accommodate a large amount of both structured and unstructured data. NoSQL databases like MongoDB gained traction among data professionals thanks to their advanced functionalities that allow them to seamlessly handle large quantities of data. MondoDB is effective, dynamic and stores data in simple forms that are easy to understand.

As a data engineer, mastering MongoDB is essential to master as a large part of your role is processing huge data volumes, and this is where this tool excels.
