Data Source
===========

To perform any analysis the wizard will first need a set of cases. Cases can be imported by 
* loading a hugin data file,
* Connect to a database service and import.
* copying cases (if any) from the network,
* or sampling a number of random cases.

Click on button "select file" to load a hugin data file, button "use cases from network" to copy cases from the network and click on the tab "Sampling" to sample a number of random cases to use as data source.  

After importing a set of cases, the Data Source pane will display a table with the imported cases, see Figure 1. To discard all imported cases click on the button "Clear Data".
