Create your own tables! Or using existing ones?

[Hessam]

According to this link , it says that it's recommended to create new tables for new module. Is it true about the existing entities? (like customer, cart, product etc.)

I think we should not create new tables for somethings like these cases, and we should modify the existing tables (e.g to add a field to customer table).

Is it true?

And when we modify the existing tables, should we override the classes? (e.g we want to add a field to customer, should we modify the corresponding class for customer- for active records)

By altering the native database tables probably you will kill the future updates of PrestaShop, that’s why you need create your own ones and handle it from a module or override file.

Thanks for your reply.

But creating my own tables means creating my own active record classes?

What if the native table has so many relationships with other tables?
