Francois Ajenstat, Tableau’s chief product officer, feels that companies unfortunately spend 80 percent of their time on Data Preparation and only 20 percent on analysis despite of the latter being a higher value task. And this has always been a constant concern for large enterprises and analytics vendors. They have been silently screaming for automation, artificial intelligence and machine learning to automate data.
Tableau Prep, according to him, is designed as a self-service tool to reshape data without scripting or coding to address the common data management problem. The ETL tool primarily automates, joins, unions, pivots and aggregates via a drag and drop visual interface to streamline all the common tasks.
Joshua Milligan who is a data consultant with a reputed firm loves the elements of fluidity and transparency in the Data Visualization tool, Tableau and strongly feels that Tableau Prep only adds more to the magic in terms of intuitiveness and seamlessness.
