Oracle is the primary database in use at Intervera and by our clients. As such, I have gained experience working with various versions (8, 9i, 10g) on large corporate servers and developer workstations. I use Oracle SQL Developer primarily during development but am comfortable with the sqlplus command-line tool. My development work has included learning the many optimizations in terms of schema definition and JDBC features that can result in significantly better read/write performance.    (Since: 1999)
