Introduction
So far, in all the previous chapters, we've created various visualizations. For each of these visualizations or sheets, we connected to a single data source at a time using the Live connect option in Tableau. However, there are going to be circumstances when data from a single database table or even for that matter a single database may not be sufficient from the point of view of our analysis. There may also be circumstances, where we may have to extract our data into the Tableau data engine and work offline to build our views in Tableau. In this chapter, we will focus on the various ways in which we can connect to data in Tableau.
