Data science is an interdisciplinary approach towards gaining valuable insights from big data. These insights help the organization to improve its operations and make efficient and smart decisions. It uses techniques such as machine learning, cluster analysis, data mining, and visualization, and uses the field of mathematics and statistics.
Why data science?
With each passing day, the amount of big data is increasing which leads to the requirements of managing and processing this big data, and data science gains its importance from this requirement. With 2.5 quintillion bytes produced each day, this group’s organizing skill gives you an added advantage. Companies such as Google, Facebook and Microsoft are looking for experts, which increases vacancies in this field. The impact of data science is spreading across all major industries such as healthcare, finance, retail, chemicals, agriculture, media, etc.
A data scientist requires mastery of certain skills to excel in this field. These include R Programming, Python Coding, Hadoop Platform, SQL Database/Coding, and Machine Learning. Besides these technical skills, a data scientist needs some soft skills: analytical ability, exceptional communication skills, visualization and presentation skills, ability to work in a team, strategic acumen, and problem-solving skills.
