my email had been rejected so I am sending it again without previous thread Thank you, I don't need a schema I just had a table of books without any data about books I wanted to store title of books and descriptions and ISBN, I searched about amazon API and google and I thought they take time. finally I googled book.xlsx and found one list of about 1000 books in excel and it was easy to import to mysql. I didn't need all the books of the world but a portion of real books which make sense .
