Their isn’t an add-in for Access, however there is a *.dll file that you can use to intergrate erlang functions into an Access database, the only issue with that is, that you have to buy it, but I wouldn’t recomend it, as it appears to be unstable, and unreliabe in it’s results
If you really want to, you can build what you are after in Excel, and then import it all into Access, but bear in mind that you will need to keep all of the constrants of Access in mind when using the import feature.
