hercules newbie

Where are the functions that executes sql queries in source code? For instance, the adding of item to the inventory table. Where can I find the actual function that has the sql statements of adding the item to the inventory table? Like, INSERT INTO inventory VALUES (item_id, item_name, etc...) <- where can I find this in the source code?

Does Hercules have a documentation on source code so that we can easily understand and make changes on it?

I have two questions. What's the most stable version of the hercules repository for a pre-renewal server? What's the most stable client and translation file for a pre-renewal server?
