As far as I know, the only two products that are currently integrated with PC-DMIS are DataPage by B&S and ANSTAT by Lighthouse Systems. Others can be integrated, but may require a simple "black box" to put the data from PC-DMIS into correct format before importing into the stats package. For example, PC-DMIS puts data out in rows. ANSTAT imports it in columns, so they developed a black box to transpose the matrix of numbers.
Additionally, the newly released Version 3 of PC-DMIS supports VisualBASIC scripting. I suspect that for most packages, it would be possible to develop VBA script that would dump the inspection results directly from PC-DMIS into the database.
Finally, I once used Quality Analyst by Northwest Analytical. I selected it because of the complimentary Quality Monitor package, which allowed me to develop very simple user interfaces for a plant-wide implementation. When NWA first converted to Windows, QM remained in DOS - I don't know where it is today. In any case, if you are looking at a SPC system beyond the CMM, you may want to look at how well the package lends itself to data input from the other sources.
