Data mining in the Dolibarr ERP package is not a feature like that of advanced packages since data analysis can be obtained through reporting tools or further integrations. While Dolibarr doesn't have robust out-of-the-box data mining features, you can always use reporting modules or export data, for example to Excel or CSV, then perform analysis using external tools such as Python, R, or specific business intelligence solutions.
For businesses that need deeper data mining capabilities, custom modules or integrations with BI tools like Power BI or Tableau can be developed to extract and analyze insights from Dolibarr's data.
