Hello all,

I'm in the process of doing some research for an upcoming project. Essentially what I need to do is to make a call to a db and insert customer info when a certain product is sold. I'm just looking at some basic guidance to see where I should begin looking.

When the customer purchases this specific product, they will be added to a special mailing list. The db only needs to know their user id and date/time of the purchase.

Any suggestions will be appreciated.
