Today, data science is more than a buzzword. To simply put it, data science is an interdisciplinary field of gathering data from various sources and channels such as databases, analysing and transforming them into visualization and graphs. This basically facilitates the readability and understanding of the data to aid in soft-skills like insightful decision-making for any organization or business. In short, data science is a combination of incorporating scientific methods, different technologies, algorithms, and more when it comes to data.
Apart from the certified courses, as a data scientist, it is expected to have experience in various domains of computer science, including knowledge of a few programming languages such as Python and R as well as statistics and mathematics. An individual should be able to comprehend the data provided and be able to transform it into graphs which help in extracting insight for a particular business.
