Everything to know about Online Course for Data Science

What is Data Science?

Data science is the study and processing of data and analytics through technologically advanced methods like software and tools powered by machine learning. It allows us to gain an insightful look into data and derive meaningful information that will help in making predictive models that can be used to make smart business decisions. Data science helps us tap into the power of data in a big way.

Thanks to widespread digitisation, today, humans produce a vast amount of data through their daily routine. This data can be used to make life better. Companies can use this data to drive innovation and market the right products and services. Governments can use it to become efficient and make their citizens’ lives safer. The applications are vast, and the possibilities arising from them are innumerable. Therefore, data science has emerged as the fastest rising subject of education in the world.

For any new learner who wishes to join an Online course in data Science it is very important to understand the subject thoroughly.

Here are some excellent data science examples:

1. Netflix –

One of the biggest platforms that makes use of data science is Netflix. In network television, only 35% of TV shows get renewed for a second season, whereas, in 2017, 93% of Netflix’s shows got renewed for a second season. This decision was possible through the use of data science.

2. Amazon –

ecommerce giant, Amazon, employs the best data scientists in the world to improve sales and user experience. Once you search for a product, you start seeing ads related to that product. You even get updates on alternate products, related products, and price drops. This is possible through data science. The data you generate through online shopping is used to optimise your shopping experience. You are even shown products according to the region you live in. That’s how detailed data science can get.

Why Data Science?

Data science is not a passing trend. It is an important subject that is going to be a permanent feature in education and business. But you still need to have strong reasons to pursue this field because data science is a specialised field.

Here are some reasons that are answers to the question, why data science is important:

  • Data science is the fastest rising field in education all over the world. The best universities and institutes in the country and world have introduced full-time data science courses at the undergraduate and postgraduate levels.
  • Currently, data scientists find themselves amongst the highest-paid professionals in the world. Data scientists are making INR 12.6 lakhs annually which is even better than software engineers, and this figure is going to get even better.
  • Data science is a field like no other. It is one of the most technologically advanced and challenging fields in the world, meaning, there are not going to be any dull moments in data science careers.
  • Just in the past decade, many fields of education and careers have become irrelevant, but this won’t happen to data science. The demand for data scientists is only going to get higher.
  • If you want to work overseas and find high-paying jobs in multinational companies, data science is the best way to achieve that because data scientists are in huge demand in the international market.

Students who join our online Data Science Course must understand that more and more companies are looking for a skilled person due to increasing popularity of Data Science Because Harvard Business Review called data science the Sexiest Job in 21st Century

Components of Data Science

To truly understand data science, you need to know about the components of data science. Each component is like a gear and their functioning is dependent on each other. Therefore, knowing about these components will help you understand data science as a whole:

1. Statistics

The collection and arranging of numerical data and analysing it and deciphering important findings is statistics. Numbers are an important part of data science as it uses many statistical models for analysis and predictions. Accurate recording and analysis of statistics are one of the most integral parts of data science.

2. Data Engineering

Once the data has been acquired, it needs to be properly stored, retrieved, and processed. This is where data engineering comes to the fore. How, when, where, and what needs to be done with the data is all a part of data engineering. Data engineering also deals with metadata.

3. Domain Expertise

Data science is always used to process data of a particular domain and for this, input from a domain expert is needed. Domain expertise brings data science together and gives it a direction, and lets you decide how to best make use of all the insightful findings.

4. Advanced Computing

Advanced computing is exactly what it sounds like. At the core of data science are many computer programs running on code. The creation, running, and  advancing of these source codes is part of advanced computing. Advanced computing is responsible for the comprehensive processing of the data.

5. Visualization

Once the data is processed, it needs to be represented in such a way that it easily communicates all the findings to everyone. Visualization also helps cover a vast  amount of data.
