Since 2005, ODTUG has sponsored annual PL/SQL-specific conferences, which are now organized in conjunction with an APEX conference: OPP and APEXposed.
This year, we will for the first time hold the joint conference in Europe, specifically in Brussels, on October 27-28.
The U.S. conference will be held in Dallas on November 10-11.
The OPP conference offers the best training value on PL/SQL around. Two days, three tracks of presentations (including almost two full days of training by me), expert presenters, including in Dallas the PL/SQL Product Manager, Bryn Llewellyn.
If you are looking for ways to get "trained up" in PL/SQL and also meet and talk with some of the best PL/SQL developers in the world, I urge you attend the OPP-APEXposed conference.
