Hi,
I am developing a website using magento. My all products are related to some studio so I need to develop a new module called “Studio” in admin panel that will contain few attributes and then I will be able to relate each product to some studio.At front end, user will be able browse studios and its related product also. Please guide me with the simplest step to develop it including data base handling function as I am not clear about the functions to use for insert, update and delete using magento. please help me as soon as possible
