Yannick,
Unfortunately, there is not a built-in tool to analyze the data from a standard TestStand database schema.
However, you could always use a VBScript within DIAdem to import data from a TestStand database. DIAdem allows you to use both ODBC and ADO commands to your database. There is a short information KnowledgeBase online
KnowledgeBase 2O08TSZL: Loading data from databases into DIAdem that may be of help if you are using DIAdem 8.1.
If you haven't worked with DIAdem and databases before, this information is covered in the DIAdem Advanced course. You can see a listing of our current course offerings and check our schedule online at
http://www.ni.com/training/.
If you have further questions about DIAdem and databases, just let us know. Be sure to include what versions of DIAdem and TestStand you are working with and what your goal is.
Hope that helps!
