## [Data Analytics: Definition, Importance, and Best Practices](/en/glossary/data-analytics-definition-importance-best-practices) ## What Is Data Analytics? Data analytics is the process of exploring, interpreting, and visualizing existing data to uncover actionable insights, identify trends, and support decision-making. It involves applying statistical techniques and analytical tools to historical data to answer questions such as “What happened?”, “Why did it happen?”, and “What does it mean?” While [data science](/en/glossary/data-science-definition-importance-key-components) makes use of algorithms and machine learning models to predict future outcomes and automate decision-making, data analytics focuses on analyzing past and present data to understand outcomes and inform decisions. ![Data Analytics](https://www.denodo.com/sites/default/files/data-analytics-diagram.png) ## Why Is Data Analytics Important? Data analytics helps organizations to gain a competitive advantage, optimize operations, and improve customer experiences.
