That's more difficult to find. How about quoting an instructor at the University of Washington that teaches both Oracle and Java (JDeveloper) courses?

Just try to keep a straight face.

The bottom line is that the arguments stand on their own. Anytime the Java developers don't want to buy it give them a schema and tell them to write an application that guarantees data integrity between two tables with a parent-child relationship. Make the tables very simple such as:

CREATE TABLE parent (
parent_id NUMBER);

CREATE TABLE child (
parent_id NUMBER,
child_id NUMBER,
somevalue VARCHAR2(20));

After they've built their demo app go in with SQL*Plus and corrupt the entire thing and ask them to explain what happened.

Once again ... try to keep a straight face.

If they tell you that you can't use SQL*Plus ... use MS Access or the free version of TOAD.

Once again ... try to keep a straight face.

That's how I taught the lesson to my class. I don't think they will forget the lesson.
