Analytics combines the use of mathematics and statistics with computer software to derive business knowledge from data. Analytics can be segmented into four types—descriptive, diagnostic, predictive, and prescriptive—as described by Gartner. Descriptive analytics focuses on describing something that has already happened, and suggesting its root causes. This involves the observation of historical data to distinguish the patterns or “descriptions of past events” in order to gain insight by implementing searchable databases. Descriptive analytics, which remains the lion’s share, typically hinges on basic querying, reporting, and visualization of historical data. Descriptive analytics is typically what is executed by traditional business intelligence platforms.
