There is a competition to outperform Google, Facebook, Apple, Amazon, and Netflix. Since big data is the most effective tool to learn about consumer behaviour, it has become essential to all businesses. Big data is the capacity to manage growing amounts of data and process a large amount of data in simultaneously. The analysis of this large data is known as data science. Future decision-making will require us to analyze vast amounts of data in real-time and take appropriate action, therefore data science is crucial. An insurance company, for instance, must assess the customer’s risk before deciding whether to provide them an insurance coverage. Or, if a loan is to be given, the loan is authorized or denied based on the customer’s credit score. Therefore, in this scenario, a significant amount of data is needed for analysis before a judgement can be made. Furthermore, computers are becoming more adept at learning from data and making predictions as a result of the growth of big data and improvements in hardware technology. Data science will therefore be crucial to the development of internet enterprises in the future.
