title: Can Tableau Desktop be automatically refreshed when the database is updated
body: <p>I'm using Tableau Desktop 9.0 to create a visualization  by extracting the data from DB2 database. But this database is updated everyday. That is, at the every time the data in the database changes. So is it possible for me to schedule a task of refreshing the extracted data source automatically at specific interval of time so that, after updating the report should reflect the results accordingly. Can this be done through Tableau Desktop automatically?  The main thing is that it can easily be done on Tableau Server as known. But I cannot afford for a Server so I'm trying to get an answer is it possible with the Tableau Desktop or not.</p>
