In the menu under the header Tables you find Data tables which are used to populate the Data tables questions as shown in figure 1.

 

Figure 1, data tables

When creating data tables you have the option to create data tables that are linked and data tables that are not linked. In this tutorial we define the not linked data table Colors with a list of colors and the linked data tables Province, District and City whereby each District has a parent Province and each City a parent District. How this is done is shown in figure 2, as you can see for the linked tables the District table has the parent table Province and the City table the parent table District. The Colors table is not linked and has no parent table, also the Colors values do not have a parent value.
