Data science is a multidisciplinary approach to obtain valuable insights from Big data. These insights help an organization improve its business operations and make efficient and intelligent decisions. It uses techniques such as machine learning, cluster analysis, data mining, visualization and uses the fields of mathematics and statistics.
Why Data Science?
As the day goes by, the amount of Big Data increases, leading to the management and processing of this Big Data, and Data Science gets its importance from this requirement. With 2.5 quintillion bytes produced each day, the ability to organize this set gives an added benefit. Companies such as Google, Facebook, Microsoft are looking for experts, which increases the vacancies in the field. The influence of data science is in all major industries such as healthcare, finance, retail, chemistry, agriculture, media etc.
Data scientist requires mastering certain skills to excel in the field. These include R programming, Python coding, Hadoop platform, SQL database / coding, machine learning. In addition to these technical skills, a data scientist needs a number of soft skills: analytical skills, exceptional communication skills, visualization and presentation skills, able to work within a team, strategic insight, problem-solving skills.
