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 🙂
– 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.
