API between SQL Ledger and OS Commerce

Greetings We need an API between SQL Ledger and OS Commerce (so once a mysql and once a postgres database server) As well customers ,as products as well orders must be synchronized between the database of sql ledger and of Os Commerce both sides need a "wishlist" - i thought using the combined product under sql-ledger, but i am open for any other suggestion Many different modules for export do already exist - what we need is a combined all-in-one solution for quickly synchronizing the data from the shop to the nventory
