What is data science?
Data is considered the new oil. It is the most valuable and precious asset at present. The big giants like google are totally based on data they obtain. There is a popular saying like “your intelligence is only as strong as the data that backs it”, this explains the importance of the data in human life. The major problem in the modern world is finding insights into data. Data abundance is making it difficult for organizations to get the right insights of data. Data science plays an important role to deal with unstructured raw data gathered by various sources. Data science is the study of a combination of mathematics, statistics, programming, and capturing data in ingenious ways, One of the major purposes of Data Science is to derive hidden patterns & trends from the data. This data can be used by businesses to enrich their customer’s needs.
Application of data science
Data Science has been proved successful in creating a vast impact in nearly every major field. It has transformed the working of innumerable sectors & still on its way to explore the remaining untapped areas. Some of the core sectors include:
Financial institutions have used data science to predict future values, automating financial tasks etc. Thus enhancing their user needs.
Data Science plays a significant role in the healthcare sector. Data science has created wonders in this sector. It has helped in early detection and prognosis of diseases, helped monitor patient’s health.
Data Science has transformed the E-commerce industries in a variety of ways. It has helped industries to showcase perfect items to their customers by studying their search patterns and thus maximizing their profits.
