Tableau

Tableau is a visual analytics platform designed to help users explore, analyze, and share data insights. It enables connection to a wide range of data sources, from spreadsheets and cloud applications to enterprise databases and data warehouses. Its primary purpose is to transform raw data into interactive, shareable dashboards and reports that support data-driven decision-making across an organization.

Tableau offers a drag-and-drop interface for building charts, maps, and dashboards without requiring coding skills, while still supporting advanced calculations and custom expressions for power users. It integrates with popular data sources such as SQL databases, Snowflake, Google BigQuery, Salesforce, and Excel, and supports live queries as well as in-memory extracts for performance optimization. Built-in features include data blending, data preparation with Tableau Prep, geospatial analysis, and robust filtering and drill-down capabilities. Users can publish dashboards to Tableau Server or Tableau Cloud for secure, browser-based access, governance, and collaboration.
