Career Opportunities in Data Science

It’s encouraging to see that people all over the world are looking for career opportunities in the IT sector. But did you know that if you are not dedicating at least 5 hours per day to learning and training, it is difficult to pursue a career in the IT sector? Today, we’ll discuss whether a career in data science will be advantageous or not to you in the years to come.

What is Data Science?

In plain English, a data scientist’s job is to analyse data to find insights that can be put to use. Finding the data-analytics issues that present the organisation with the most opportunities is one example of a specific task. choosing the appropriate variables and data sets.

Subject used to learn to be a data Scientist

So, gentlemen, Some subjects are common, such as Excel and SQL, but others, such as Python, Machine Learning, and Deep Learning, etc may be unfamiliar to you. Here we talked about all the subject which must be cover before persuing Data Science.

Let start from Data Analytics

Before Moving on to Data Science we must be expert in the subject like Excel, Power-Bi,SQL, R programming and Python.


First we talk about Excel, You can easily and quickly view, create, edit, and share your files with others using the Excel spreadsheet app. While viewing and editing workbooks that are attached to emails, you can also create spreadsheets, data analyses, charts, budgets, and other documents.

It is used in data analysis, accounting, finance, or any other industry. Your data and office follow you wherever you go. From your phone, you can instantly create charts, perform data analysis, and annotate your documents.

SQl and PowerBi

Excel is used for small Dataset but if you have to work on large Dataset then SQL and PowerBi are best option. The next level of data analysis is achieved when SQL and Power BI are used together. It is simple to connect the SQL Server to Power BI and import the data there. Users of Power BI can quickly switch between connections to run in-memory queries on a bigger dataset.

R Language

R offers a wide range of graphical and statistical techniques, including time-series analysis, classification, clustering, and linear and nonlinear modelling. It is also very extensible. R offers an Open Source alternative for those interested in participating in statistical methodology research, which frequently uses the S language as its preferred vehicle.

The simplicity with which well-designed plots of publication-quality can be created using R, complete with mathematical symbols and formulae where necessary, is one of its strengths. The user still has complete control despite careful consideration being given to the graphics’ minor design decisions’ defaults.


The general-purpose, interactive, object-oriented, and high-level programming language Python is very well-liked. Python is a garbage-collected, dynamically typed programming language. Between 1985 and 1990, Guido van Rossum created it. Python source code is also accessible under the GNU General Public License, just like Perl (GPL).

Programming languages such as procedural, object-oriented, and functional are supported by Python. Python’s design philosophy places a strong emphasis on code readability through the use of deep indentation.


Another visualization software you have to learn is Tableau. Mostly companies prefer this software due to its wide storage and high demand. This software helps you to give accurate visualization for any insight you create. The Tableau course takes minimum 2 months to understand its command , import and export Data, creating insight and so on.

Note:-When you have mastered all of these topics, we will progress from Data Analytics to Data Science.

Now when it comes to Data Science then we used to talk about Machine Learning and Deep Learning and this whole process comes under AI(Artificial Intelligence).

What is AI?

The simulation of human intelligence functions by machines, particularly computer systems, is known as artificial intelligence. Expert systems, natural language processing, speech recognition, and machine vision are some examples of specific AI applications.

Machine Learning

The scientific discipline of machine learning enables computers to learn without explicit programming. One of the most intriguing technologies that has ever been developed is machine learning. The ability to learn is what, as the name suggests, gives the computer a more human-like quality. Today, machine learning is being actively used, possibly in a lot more places than one might think.

Deep Learning

Artificial intelligence (AI) and machine learning techniques called deep learning model how people acquire specific types of knowledge. Data science, which also includes statistics and predictive modelling, includes deep learning as a key component. Deep learning makes this process quicker and simpler, which is very advantageous to data scientists who are tasked with gathering, analysing, and interpreting large amounts of data.

What people think about this course …I don’t care but its really a booster for your future. You have to learn all these subject and have to do practical more than theory to get a masterclass job for your better future. Its my humble request to all of you who are reading this article that before doing this course you have to prepare yourself completely. You have to be mature enough and give minimum 8-10 hours per day for better understanding of Python and other valuable subjects. This course might take time of 1-2 years to complete but after that the doors are open for you in any company and field worldwide.
