The SPC Toolkit only provides the means to analyze some data. It does not provide anything with which to get the data. You will have to do that yourself. NI sells tools such as the Database Connectivity Toolkit and Diadem that you can use to extract information from an Access database. You can design a program that generates the queries you want and then use the SPC functions on the data you're read. As an example, say you wanted to run a pareto of test failures similar to the Pareto Example VI that comes with the toolkit. The example has an array control with some values entered. You would have to replace the array constant with an actual query that returned the test failures.
Note that there are alternative ways than the SPC toolkit and writing your own queries. You might want to look at NWA Quality Analyst (http://zone.ni.com/devzone/conceptd.nsf/webmain/93387371274B543786256FFF008194FD?OpenDocument&node=1...), SPCStand (http://www.vidaq.com/spcstand/index.htm), and Arendar (http://www.vi-tech.com/products/Arendar/Arendar_MainScreen.php3). The queries and data analysis can also be done just in Access with custom reports and forms.
