Big Data vs Data Science | The Big Data Problem | Need of Data Science

Data Science deals with structured and unstructured data. In principle, everything that relates to data cleansing, preparation and analysis lie within the scope of Data Science. Big Data implies huge data volumes that cannot be processed effectively with traditional applications. Big Data processing begins with raw data that is not aggregated and it is often impossible to store such data in the memory of a single computer. Data Science looks to create models that capture the underlying patterns of complex systems and codify those models into working applications. Big Data looks to collect and manage large amounts of varied data to serve large-scale web applications and vast sensor networks.
