Chapter 5 – Data Handling & Data Sources

Chapter 5 introduces how Wolfram Mathematica is used to work with data from external sources. It explains the complete process of handling data, beginning with locating and organizing data files so that Mathematica can access them correctly. The chapter then focuses on importing data from different file formats into the system, including practical examples such as importing data from Microsoft Excel. It further explains how data can be exported from Mathematica into other formats for reporting and sharing purposes. Finally, the chapter covers data collection and introduces working with real-world datasets, including financial data, while demonstrating how imported data can be manipulated, analysed, and visualised using Mathematica’s computational and graphical tools.
