[Zope-dev] DB Connection Question

Hi, I have written a Product the uses a Databaseconnection to MySQL, that works fine. but the connection in coded into my Product, and now i want to use a Zope DatabaseConnection added to the same folder. How does this works, it is very important for me, because we want to change to another database, and because this fact it is very useful for me to use an existing DataBaseConnection Object from Zope in my Product to connect to a DataBase.
