What is Data Science?
Data science is the field of study that combines subject-matter knowledge, mathematics, statistics, artificial intelligence, and computer engineering to draw out useful insights from data.
The primary purpose of using data science is to collect data, process it, analyze it, and filter information from raw data.
Data science uses the most advanced hardware, programming languages, and algorithms to resolve data-related issues.
The future of artificial intelligence lies in it.
Simply expressed, data science is all about:
- Presenting the right questions and analyzing the raw data
- Using various advanced and effective algorithms to model the data
- Visualizing the data to gain a deeper understanding
- Understanding the data to find the final result and make better decisions
What Does a Data Science Engineer Do?
A data engineer is responsible for creating systems for gathering, validating, and preparing high-quality data. Data engineers collect and prepare the data, while data scientists use the data to support better business decisions.
The data engineer/ strategist’s job is to find and integrate new datasets that can be used to expand the functionality of the business and collaborate with the technical team to develop data products.

How To Start Your Data Science Career?
There are a few questions you should ask yourself before planning to pursue a career as a data scientist:
- Do you love statistics, numbers, and graphs? Data science is entirely based on Maths and statistics. If you don’t like math, statistics, and numbers this is a red flag for you. If you don’t like working with numbers, you will find your job frustrating later in your career.
- Before advancing to a justified data scientist position, are you willing to learn and work at the entry-level?
- Are you able to program easily? Data scientists should be comfortable using a variety of programming languages, including R and Python.
You can move forward and begin learning the data science abilities once you have a positive answer to the questions above.
Let’s take a look at the steps to Becoming a Data Scientist
Step 1. Get an undergraduate degree in data science
To become a data scientist, you must first get an undergraduate degree in data science or a closely related field.
Most employers will want to see a bachelor’s degree to hire you as a data scientist. Getting a bachelor’s degree in a field like data science, statistics, or computer science is an excellent way to get started in this profession.
Otherwise, if you’re looking for a data science bootcamp, post-graduation course or master’s in data science, GreatLearning’s online data science courses are a good place to start.
Step 2. Develop your skill set
Even though a Bachelor’s degree may give you a theoretical understanding of the topic, it is important to brush up on your programming, technical, and non-technical skills.
Below are some of the most necessary skills you require for this job.
- Technical skills like Machine Learning, Deep Learning, Processing large data sets, Data Visualization, Data Wrangling, Statistical analysis and computing, Mathematics, Programming, Statistics, and Big Data.
- Non-technical skills like Strong Business Acumen, Strong Communication Skills, and Great Intuition on data that you are working on.
Check out our list of top data science books that will upgrade your skill sets.
Step 3. Get Certifications in Data Science
Getting Data Science Online Courses & Certifications is a great way to showcase your skills. Instead of buying random data science courses on the internet, try to get free certification from trustworthy sources like Simplilearn, Naukri, and LinkedIn.
Here are some free certifications of data science tools to help you on your way:
- Tableau Certification Training Course
- Power BI Certification Course
