Data scientists. Data scientists work closely with business stakeholders to understand and have a clear perspective on their goals and determine how data can acquire them. They design the data modeling processes, generate algorithms and predictive models to extract the business’s data needs, and assist in analyzing the data and share insights with associates.

Business intelligence (BI) specialists take on the role of designing and implementation of  BI software and systems while incorporating them with databases and data warehouses. Business Intelligence provides a readout on the current status of the business by tracking key operations metrics in real-time, giving the business descriptive, instead of predictive, data.
