What is Data Science?
Data science is the study of extracting valuable information and insights from data using various algorithms, processes, and scientific methods. It is related to big data, one of today's most popular and in-demand skills. Data science comprises mathematics, computations, statistics, programming, etc., to gain meaningful insights from large amounts of data in various formats.
What is Data Analytics?
Data analytics involves looking for trends in large datasets to understand what they mean for a particular business area. This information can then improve or take action on specific problems. By understanding the patterns hidden in their data, businesses can make better decisions that lead to success. This process of extracting insights from data is known as data analytics, forming an important part of business intelligence.
Data Science vs. Data Analytics
Though there is a common misconception that these two terms can be used interchangeably, the is a big difference between data science and big data analytics. Data science is the umbrella term for a group of fields that deal with mining large datasets. On the other hand, data analytics is more focused and can even be considered part of the more extensive process. Analytics is about finding actionable insights that can be implemented immediately based on existing queries.
Difference Between Data Science and Data Analytics
Another difference between data science and data analytics is that data science is more about asking questions and understanding trends than finding specific answers.
The field is focused on using existing data to establish potential trends and identify better ways to analyse and model that data. This makes data science an essential tool for businesses and organisations who want to make the most of their data.
Here is a table to help you better understand the difference between data science and data analytics:
Features of difference
Python is a commonly used language along with C++, Java, Perl, etc.
Knowledge in Python and R Language is essential
