The job of a Data Scientist is to deliver the necessary data to the user/client from a vast amount of data. There are many companies you have vast data stored in their database and they will have to provide the data requested by the user quickly so to maintain the quality of user experience. Searching through all the data to find the requested data is not suitable in such cases. Here, the Data Scientist comes into play. A Data Scientist will have to find a pattern of data and find a way to get it delivered to the end user quickly.
