[Zope] Zope Products and SQL

I haven't seen this mentioned and I didn't find it in the archive, so I feel inclined to ask: Is there any way (aside from importing database modules ie PoPy) to execute SQL from a Zope Product? Is it feasible to make the product inherit from ZSQL methods and have them that way, or it is just easiest to use ZClasses? I use SQL in almost everything, but I also like Products and want to know the best way to mix them. Thanks. Troy
