Data mining is a technique used to uncover previously unknown and potentially useful knowledge from large datasets. It turns data into actionable information for better decision making. Delphi incorporates a collection of high-performance data-analysis components known as the Decision Cube. The Decision Cube offers an easy path to powerful data analysis in an application. This paper describes a simple approach for data mining using the Decision Cube components of Delphi. It requires only some drag-and-dropping and property-setting, with no need for manual coding. It does not require special knowledge of data mining. At the end, an example is offered.
