For five years, no in-depth study, only their own experience How to learning, inadequacies also hope forgive me.

The front is a basic introduction, here is my sort of learning experience, mainly from the PL / SQL and databases, both introduced:
A, PL / SQL
- Basic grammar
- function
- abnormal
- optimization
Two, Oracle database
- Examples (memory, processes)
- file
- management
Work on different skills requirements are different, so please choose the focus of study according to their own circumstances, of course, know how to work more for the more favorable, the next section I will detail.
