Data science is a process of getting insights from your data using
technology. Microsoft Excel can not work on this huge volume of data
because the data is not data it is big data all right so for big data you
need advanced technology and tools such as Python and R these are
the programming languages that data scientists use to perform data
analysis for data store and distributed computing. Data scientists
spend their time on the next step after data cleaning and visualization
is building a model. Data scientists then deploy their model to
production and then start collecting insight or start doing predictive
analysis. Amazon uses data science to give you product
recommendations the video recommendations on Amazon Prime it
