What Does a Data Engineer Do?
Data engineers build pipelines that automatically sort data lakes into readable data for analysts and data scientists. They may also tune databases to make them easier for people to analyze. To do their job, they need to build good pipelines and data stores and work with a team to figure out the best ways to sort data.
These three duties will form the core of your data engineering career.
One of a data engineer’s main roles is building data pipelines. These pipelines are more complicated than they may seem on the surface level. In companies the size of Apple or Microsoft, data engineers will be responsible for dealing with petabytes of data regularly.
The pipelines must be built in a way that maximizes usefulness for everyone. You’ll be building algorithms that can quickly analyze and sort massive chunks of data to get people what they need to do their jobs as efficiently as possible.
Builds Data Stores
Data scientists have to turn raw data into useful, readable data. To that end, the algorithms they build have to streamline the process.
Data engineers take piles of raw and unsorted data in data lakes and refine them before placing them in a data warehouse. These are processed and human-readable data storage. This means that the data has to be accessible at any time to anyone who needs it.
Adapts to Change
Data analysts and scientists have different needs depending on the industry. Financial institutions have different needs for their data when compared to a fashion retailer, for example.
No matter where you land as a data engineer, you’ll have to adapt to the industry and be ready for constant change. Needs will change as new projects come in and old ones go out. Because of this, you’ll have to rework old algorithms and introduce new ones regularly to keep your organization ahead of the curve.
Essential Data Engineer Skills and Certifications
Data engineers need to be able to use programming languages, data warehousing tools, and cloud computing architecture. Some of the biggest names in tech offer certifications that verify one’s data engineering capacities.
Once you’ve mastered these skills, you’ll be able to obtain certifications that will improve your job prospects.
Data Engineer Skills
Proficiency in Multiple Programming Languages
The two most popular programming languages for data engineers are Python and SQL. Python is a great general-purpose language that can serve many functions. SQL is a language that’s designed for managing data in relational databases.
On some occasions, you may also have to use R, Java, MATLAB, and more. The programming language you’ll use will depend on your job. That said, it’s good to lay a foundation in Python and SQL when you’re new in the field.
As we’ve mentioned above, data warehousing is the act of taking raw data and transforming it into one or more pools of indexed and usable data. There are a few ways to do this, so it’s good to know which works best for your situation.
Amazon Redshift is a tool from Amazon Web Services that’s been one of the more popular solutions for data warehousing. Naturally, Google has its own data warehousing solution in Google BigQuery. Both can handle petabytes of data in seconds, simplifying the sorting process for important data.
You’re going to need to borrow some power from the cloud to store the vast amount of data for any organization. A good data engineer has to know how to take advantage of their platform. If you’ve mastered the architecture of a cloud computing framework, it will be easier for your company to handle more data.
