SQL database was a large amount of tables alike and if you try to add a feature that it doesn't implement yet (such as drop shipping capabilities) I couldn't figure it out because its not as simple as creating a new set of forms like in Django you basically have to understand the whole system and I think the task would take a year. It would have been better to integrate an existing system instead.
