Mary Hunsaker Gable has been designing, administering, and developing applications, databases, and education solutions for the Oracle database for over twenty-three years beginning with version 5 of the database. With no choice but to use Pro*PL/1 and Pro*C, she was excited to take advantage of PL/SQL when it was initially released and used it along with Oracle’s Forms and Reports tools to develop her company’s custom accounting software. While watching PL/SQL grow into a robust (and sane) environment for Oracle development, Mary combined her passion for Oracle with her passion for teaching and created Preferred Training Solutions in 1993. In addition to PL/SQL, her favorite, she regularly teaches the full curriculum of Oracle database administration and application development courses worldwide for many Fortune 100 companies such as Hewlett-Packard, IBM, Fannie Mae, Northrop Grumman, various universities, and local, state, and federal government. Mary is active in the Oracle user group community and has authored and presented dozens of papers for various Oracle user groups. She founded the Hampton Roads Oracle User Group (HROUG) in 1993 and continues to serve the local user group community as a board member, frequent presenter, and IOUG representative. She has been chosen by Steven Feuerstein to lead the PL/SQL Fundamentals track at OPP conferences OPP '07, OPP '08, and OPP '09 being held in Atlanta, Nov. 10-11, 2009.
