I highly recommend these if you are serious about Oracle. In this page, I don’t explain everything in detail for one reason – I don’t want to copy the Oracle documentation where everything is described in the best way possible. I am trying to extract and highlight the most important information and serve them in a lucid way 🙂
Books
– I am not fond of books in general when it comes to technical documentation. If you are serious about Oracle, turn to Oracle’s official documentation.
Web pages
Oracle’s official documentation – the best documentation about Oracle. There are no books or other sources that might explain it better than this web page.
