Data science is a form of outsourcing that involves the delivery of information gleaned from advanced analytics applications run by data scientists at an outside company to corporate clients for their business use.
A DSaaS provider collects data from clients, prepares it for analysis, runs analytical algorithms against the refined data, and returns the findings generated by the algorithms to the customers.
DSaaS typically requires clients to upload their data to a cloud database or a big data platform, where the service provider's team of data engineers and data scientists can work with it.
