Data engineering is thriving and flourishing day by day.
It's becoming one of the most valuable career options and a highly lucrative
one at that.
Every organization is built and works on data. For smooth
sailing and better decision-making abilities of an organization, a structured
framework of data is required. And that's what data engineers are for.
Let's understand data engineering more thoroughly.
What Is Data Engineering?
Data engineering can be defined as sourcing, altering, and
organizing data from different systems to build reliable systems or mechanisms
for data collection.
Who Are Data Engineers?
Every firm, whether small or large, has a hefty amount of
data that is required for various purposes like assembling, and authenticating
data in a highly functional state before it reaches other parties like data
analysts or scientists.
The people intended for this procedure are known as data
Data engineers work with detailed methodologies for
collecting, transforming, and organizing data into useful sources.
Data engineers are the gatekeepers and facilitators for the
seamless flow and storage of data. They design, construct, install, test, and
maintain scalable data management systems.
More About A Data Engineer's Job
A data engineer is primarily responsible for the following
- Executing, verifying, and developing software systems.
- Extracting data from one source and loading it into
another with minimal to no errors.
- Working on numerous scripting languages and comprehending
the nuances to integrate the systems efficiently.
- Discovering new ways to extract data and using the
- Co-operating with other team members, like data
architects, data analysts, and data scientists, for creating robust data
pipelines and systems.
Top tips for becoming an Efficient Data Engineer
Become an expert at programming
Before you begin working on data engineering tools, you
should know the fundamentals. You will have to develop the required skill set.
To become a thriving data engineer, you need to brush up and level up on
foundational programming skills.
The data engineering world mainly comprises two technologies
â€“ Python and Scala. Consequently, you must have proficiency in writing scripts
as well as creating software in Python.
Scala, on the other hand, is produced on strong functional
programming foundations. It operates on the JVM and therefore is compatible
with other Java libraries.
Get in-depth knowledge of the database.
To be a data engineer, you have to have an exceptionally
firm grip on database languages and instruments. This is one of the very basic
requirements if you are wandering around for a job as a data engineer. You
should have knowledge of how to compile, store, and query the information from
the databases in real-time.
Some of the commonly used databases are - SQL Databases,
NoSQL Databases, PostgreSQL, MySQL, MSSQL
You should have in-depth knowledge of at least one of the
databases mentioned above.
Data warehouse architecture
Virtually every organization inquires about data warehousing
and ETL (Extract, Transform and Load) experience for the role of a data
engineer. For data warehousing, there are tools available such as Amazon
Redshift, Microsoft Azure, Google BigQuery, Snowflake, etc. Some of the widely
used ETL tools are Xplenty, AWS Glue, Alooma, Oracle Data Integrator, etc.
Hadoop based analytics
Organizations seek a strong understanding of Apache
Hadoop-based analytics when you apply for the post of a data engineer.
Therefore, you need to know how to work on Hbase, Hive, or Mapreduce to land
your data engineer's dream job easily.
Basic understanding of Machine Learning
Machine Learning is an extension of Artificial Intelligence
that provides machines the ability to learn without being explicitly
programmed. Data engineering along with machine learning strives to create
predictive and prescriptive analytics for better business outcomes.
Python language is often utilized to develop Machine
Get Professional Certificate
Becoming a data engineer is not as easy as it sounds. It's
not a cakewalk, particularly when you are still a novice to the tech world. It
requires a strong and in-depth knowledge of tools, tech, and work ethic to get
a high-paying data engineering job.
Having a professional certificate in your resume will
provide you with a great competitive advantage in the market all the while
improving your chances of getting your dream job at your dream company.
Get data engineering courses from the World's top Universities. Gain Executive PG
Programs, Advanced Certificate Programs, or Masters Programs to fast-track your
Now that you know how to become a data engineer, let's talk
about what you'll earn once you land a data engineer's job.
How much does a data engineer earn?
An entry-level data engineer with little to no experience or
less than one year of experience can expect to achieve INR 4,00,676 per year.
In their early jobs (1-4 years of experience), data engineers may expect an
increment of about INR 7,37,257 per annum.
What's the difference between the roles of a data analyst and a data engineer?
Data analysts examine numerical data and utilize it to
assist businesses in making better decisions. Data Engineers are involved in
the data preparation process. They design, build, test, and maintain the entire
architecture. When compared to data scientists, data engineers do not receive
nearly as much media attention, but their average income is greater. You'll
need to be able to analyze data utilizing data analysis tools like Apache
Spark, R Programming, and IBM SPSS as a data analyst. Data scientists and data
engineers are both programmers. Data engineers, on the other hand, have a
better understanding of this skill, but data scientists are much better at data
What are the roles performed by a data engineer?
The purpose of data engineers is to build and maintain a
company's data infrastructure, which includes databases, data pipelines, and
warehouses. Cleaning, organizing, and analyzing unstructured data is the first
step. Data pipelines are pre-designed systems for processing and storing data.
A competent data engineer should have a strong understanding of data-wrangling
tools and languages, as well as a broad understanding of a variety of subjects.
With the help of professionals and attending data engineer
certification courses, you can easily learn data engineering and get a job with
good pay easily. All you require is your willingness to learn and a knack for
