Hi, I am preparing for the OCA 11g certification. there are a few oracle 11g edition: (standard edition one, standard edition, enterprise edition). which one is good for preparing for the OCA exams. Thanks a lot.
By the way, i only have experience with oracle 10g expression edition
In my opinion you should always use the Enterprise Edition for learning the product as it contains the full functionality set. Some of the OCP exams contain questions on enterprise edition functionality.
