Hello, I've learnt sql from this source: v series of oraclecoach on youtube and googling. Now, as I want to be a professional developer, what do I need to learn next? How can I make forms, reports based on my created table. How to make my database redistributable so that I can sell it. So many question arise in my mind. Can you please explain me a sequence of learning oracle? As I want to develope this type of software such as management systems and sell them, what do I need to learn more? I'm totally dependent on this forum as I've none other to help or no institution to teach me.
