The rapid pace at which technology is advancing and progressing is not news to people living in this age. Artificial Intelligence and machine learning are dominantly running the world functions and will continue to do more so in the future.
Each new day brings advancements in the field of information technology that opens new doors and opportunities for individuals seeking to pursue this field as a career path. Data Science is another technology that is leading the fourth industrial revolution.
What is Data Science?
New data is being generated each day at an unthinkable speed and in huge amounts. This data is of great relevance to the businesses and data science is a major source of capitalizing on this available data. Since we live in a data-driven world, every decision made in our surroundings is a calculated move based on the accumulated data.
Data science is a multifaceted field of data processing that makes use of quantifiable systems and technical standards. The resulting outcome is invaluable information that can help in business decision-making, strategic planning, and other uses.
