7 Decision Support Systems (DSS) (Gorry and Scott-Morton, 1971) interactive computer-based systems, which help decision makers utilize data and models to solve unstructured problems Source: Ramesh Sharda, Dursun Delen, and Efraim Turban (2017), Business Intelligence, Analytics, and Data Science: A Managerial Perspective, 4th Edition, Pearson 7

8 Decision Support Systems (DSS) (Keen and Scott-Morton, 1978) Decision support systems couple the intellectual resources of individuals with the capabilities of the computer to improve the quality of decisions. It is a computer-based support system for management decision makers who deal with semistructured problems.

21 Data Analyst Data analyst is just another term for professionals who were doing BI in the form of data compilation, cleaning, reporting, and perhaps some visualization. Their skill sets included Excel, some SQL knowledge, and reporting. You would recognize those capabilities as descriptive or reporting analytics.

22 Data Scientist Data scientist is responsible for predictive analysis, statistical analysis, and more advanced analytical tools and algorithms. They may have a deeper knowledge of algorithms and may recognize them under various labels data mining, knowledge discovery, or machine learning. Some of these professionals may also need deeper programming knowledge to be able to write code for data cleaning/analysis in current Web-oriented languages such as Java or Python and statistical languages such as R. Many analytics professionals also need to build significant expertise in statistical modeling, experimentation, and analysis.
