Graph-based or Network Data

            The data that is generated from a relationship or adjacency of objects is called graph-based
            or network data. Such type of data is found on social media websites and is a natural way to
            represent networks.


            Audio, video, and images
            This type of data is the biggest challenge for data scientists because finding objects and patterns
            turn out to be a challenging task for computers.


            Streaming Data

            Streaming data can take any of the aforementioned forms. It is not a different kind of data but it
            flows into the systems instead of being loaded into a data store in batches.




                      WHY DATA SCIENCE?

            Data  has become  an important  fuel on which industries  function  today.  For companies  to
            grow and flourish, they need data to be analysed. This analysis then helps them measure their
            performance  and  gauge  the  expectations  of the  market.  Healthcare  industries  also  use  data

            science to recognise microscopic tumours and deformities at an early stage of diagnosis. The
            person responsible for dealing with data in order to assist companies in making proper decisions
            is called a data scientist.

                       ROLE OF DATA SCIENTIST


            A data scientist is someone who uses
            data  sets  to  create  a hypothesis  and
            then works on the data set to analyse                      Subject: Application of Data Science

            recognise patterns within the data.
