I'm using Tableau Desktop 8.0 to create a visualization (.twbx file) by extracting the data from MySQL database. But this database is updated on weekly basis. That is, at the beginning of every week 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(i.e. on weekly basis in my case) so that, at beginning of every week the data source should be refreshed according to the new updates in database and the report should reflect results accordingly. Can this be scheduled through Tableau Desktop automatically? The very fact that it can easily be done on Tableau Server is known to me. But I cannot afford for a Server so trying to get an answer if the same is possible with Tableau Desktop edition.
