# 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”.
