Tableau is one of the most talked-about Data Visualization tools to transform a raw set of data into a format anyone can easily understand. Tableau generates visualizations as worksheets and dashboards that provide insights for businesses, driving growth and performance. It is mainly used to analyze data with limitless data analytics. Tableau can connect to various kinds of data sources; it can extract data from multiple databases and data formats. You can also connect it to different databases as various types of database connectors are available for Tableau. You can then connect the collected data to Tableau Desktop, which is the data engine of the platform. It pulls up the data from various sources and develops visualization that can be shared with users in the form of static files. The latest feature introduced in the platform – Ask Data – lets users ask questions and get the data instead of sourcing the data from the files or databases. For example – one can ask what is the most expensive city in the country and directly get the result.
