Data Analytics encompasses various types of analysis that differ in their complexity, temporal focus, and value contribution. Each type of analysis has specific application areas and often builds on the results of the previous one. Descriptive Analytics: What happened? Processing and visualization of historical data to represent the current state Identification of patterns, trends, and anomalies in past business processes Creation of a solid data foundation for further analyses Typical methods: Reports, dashboards, scorecards, basic visualizations Diagnostic Analytics: Why did it happen? Deeper analysis of causes and relationships behind observed events Identification of correlations and causal relationships in the data Drill-down analyses to investigate specific patterns or anomalies Typical methods: Data mining, correlation analyses, multidimensional analyses Predictive Analytics: What will happen? Prediction of future events and trends based on historical data Development of statistical models and algorithms for forecasting Quantification of probabilities and risks for various scenarios Typical methods: Regression, machine learning, time series analyses, forecasting models Prescriptive Analytics: What should we do?

A successful Data Analytics strategy requires a balanced interplay of various components that go far beyond technology and data. A comprehensive approach considers business, technical, organizational, and cultural aspects.
