THE SYLLABUS
INTRODUCTION
Tableau is a visual analytics platform that is revolutionizing the way we use data to solve
problems by enabling individuals and organisations to make the most of their data.
Tableau is a great data visualization and business intelligence application that can be used to
report and analyse massive amounts of data. Salesforce purchased Tableau in June 2019, an
American firm founded in 2003. It enables users to build various charts, graphs, maps,
dashboards, and stories for visualising and analysing data in order to aid in business choices.
Tableau offers several unique and fascinating features that make it one of the most popular
business intelligence (BI) applications.
FEATURES OF TABLEAU


Tableau supports powerful data discovery and exploration that enables users to answer
important questions in seconds.

TABLEAU IN NEW TECHNOLOGIES
AI and Machine Learning Integration

Tableau GPT and Tableau Pulse: Introduced by Salesforce, these tools leverage
natural language processing (NLP) and AI to enable conversational data queries.
Users can simply ask questions in natural language, and Tableau provides visual
insights without requiring deep technical expertise.
Data Cloud and CRM Integration

Salesforce Data Cloud: With Tableau’s integration into Salesforce, data from
different sources can now be centralized in a single, unified platform, providing better
insights across customer data, CRM, and more. This integration is particularly useful
for real-time data analysis in industries like retail, finance, and healthcare.
