What is Data Science?

According to Oracle, Data science combines multiple fields, including statistics, scientific methods, artificial intelligence (AI), and data analysis, to extract value from data.  Data scientists are individuals that use a variety of talents to analyze data acquired from the web, smartphones, customers, sensors, and other sources in order to generate actionable insights. Data science refers to cleansing, aggregating, and changing data to undertake advanced data analysis. Analytic applications and data scientists can then review the results to uncover patterns and enable company leaders to make informed decisions.

How Important is Data Science?

Data science is a rapidly growing field, but it is still in its infancy, according to industry experts. Data science is important because it produces enchantment and lessens the terrors of uncertainty for businesses. Industries require data science and data to assist them in making intelligent decisions. Raw data is churned into valuable insights via data science. As a result, a trained Data Scientist will extract useful information from whatever data he encounters. He assists the company in making the proper decisions. He is a master at making solid data-driven decisions, which the company requires.
