Don't post articles when you're "just beginning" - that's going to be sod all use to anyone. It's good that you're keen to post articles but you should only do that when you've got something useful to convey. Learn about Oracle, find your favourite bits, then max out your knowledge on those bits: read the Oracle documentation on (and around) those subjects in FULL, use the knowledge for at least 4 hours a day for at least a year, *then* and *not before* you might have some skills worth sharing.
