To be able to load the event data from the database, Interactive PMCube Explorer requires some meta-data on the database schema which is provided by an XML-based meta-data file. To create this file, Interactive PMCube Explorer provides a meta-data editor that can be opened from the Tools tab.
To create a new meta-data file, click on 
. In the pop-up window, select the type of your data cube. You can choose one of the following data cube models:
Default: The default PMCube data cube model
Direct Access: Data cube model for directly accessing an operational database using OLAP operations
PMC: The Process Cubes / PMC data cube model according to van der Aalst and Bolt
You can click on 
to save the file to disk or on 
to load an existing file from disk. Furthermore, you can click on 
to check if your meta-data is valid.
The editor window provides a number of different tabs to edit the meta-data file which are explained on the following pages in more detail.
