摘要：The article presents the concept of Business Intelligence and their influence on decision
making. Examining Business Intelligence systems was accomplished by theoretically
comparing of four systems: Microsoft Power Bi, IBM Cognos, Oracle BI, and SAS, focusing
on “functionality”, “performance”, “usage” and “cost” criteria. Functionality testing was
done through the Power BI system using a HORECA industry dataset, namely a café retailer.
On this dataset has been applied data mining concepts as cluster analysis, KNN classification
analysis, and association study, to determine the frequently encountered templates, to
categorize buyers into various key categories, and to help the business thrive.
