Data Engineering deals with building systems to collect, store, analyze, and craft meaningful data. Its use-case spans over every industry wherever you find some form of data.
And data engineers are the backbone of such industries. Without making sense of the data available, organizations and analysts will remain clueless.
But, how do you become a data engineer? Is it a good career option for the present? Does it have the potential for the future?
In this article, I shall present answers to all of your questions along with some course recommendations to start your career as a data engineer, if you decide.
How Do You Become a Data Engineer?
A data engineer needs to develop several skills, which come with experience and certifications. To get a head start, you need to have mastery over coding languages like Java, R, Scala, Python, SQL, and NoSQL.
You will have to explore databases, data storage, automation/scripting, machine learning, data security, big data, and cloud computing. Of course, the requirements might vary as per the job role, but in other words, you must know a wide range of things to become a data engineer.
So, it is unlikely that you get to be a data engineer as soon as you start your career. You will have to start as a software engineer or analyst and then move up to a data engineering role.
Is Data Engineering a Promising Career?
Data is the most precious asset now, even when compared to natural resources like oil.
Companies invest trillions of dollars to build ways to collect, process, and store data. It is not just about your personal information, but everything in the world.
And it’s growing at a rapid pace.
As the value and amount of data increase, the demand for data engineers will also increase.
As per a 2021 LinkedIn report, data engineering was one of the top jobs on the rise. And, it is expected to be one of the most trending sectors in the future as well.
If talking about its potential—as long as data exists, there will be requirements to build systems to process and make it useful. So, it definitely sounds impressive for a career choice.
How to Approach Data Engineering as a Career Path?
Data engineering can be a challenging career path. Where do you start? What exactly do you need to learn?
It is important to note that most data engineers learn on the job without even realizing it. You start as a Data Scientist or Analyst and hone your skills to take up a better position as a Data Engineer.
Let me mention some key highlights for the things you have to know to advance your career as a data engineer:
- Programming skills are a must: For starters, you need to know the basics of Python and R. These are the two most significant languages for the field. You can also explore more languages; you cannot ignore these two languages.
- Database knowledge: Considering that you will be dealing with raw data, you need to know SQL, how to optimize SQL queries, manage a database system (or RDMS—Relational Database Management System). The basics will give you a head start, but you need the knowledge to manage complex database systems for businesses.
- Data warehousing: While this is possible only when you are learning on the job, you will have to assist data engineers in managing unstructured data and assessing it for business decisions.
- Operating system knowledge: You should have a good command of using UNIX-based systems, Linux systems, Solaris, and Windows systems as well.
- Machine learning: At least, the basics of machine learning for data modeling and analysis should be of help.
- Big data tools: Considering you will be dealing with massive amounts of data, it is best to know some use-cases of big data tools like Apache Hadoop.
Note that these are not the exact prerequisites of the job role you want. We only list these to give you a head start and explore the basics/necessities to become a data engineer.
You may need to learn more about other tools or programming languages as you progress in your career path.
In addition to some of the above information, here are some course recommendations to make it easy for you to learn what’s required to become a data engineer:
