What Is Data Analytics?

Data Analytics examines, cleans, transforms, and interprets data to discover valuable insights, patterns, and trends. It is pivotal in helping businesses extract actionable information from large and diverse datasets. Data analytics encompasses various techniques, including descriptive analytics (summarizing data), diagnostic analytics (identifying causes of events), predictive analytics (forecasting future trends), and prescriptive analytics (offering recommendations for decision-making).

What Are Open Source Data Analytics Tools?

Open-source Data Analytics Tools are software applications or platforms that provide data analytics capabilities while adhering to open-source principles. These tools are developed and maintained by a community of contributors, and their source code is freely available for anyone to use, modify, and distribute. This open approach fosters collaboration and innovation, making it accessible to businesses of all sizes.
