Name, Age and Sex
Which tutorial, may help me in this regard.
I did a Google search on "tomcat netbeans postgresql tutorial" and
turned up some likely-looking links.... should work for you too. :-)
Right, and as a hint: dont store the AGE of a person, store the
birthdate instead.

Another hint: don't store "sex" (do/don't do?), but "gender" (even
better if tristate: male/female/not informed or "other").
I already had lots of trouble with customers asking me to adjust my

this very subject, and it was an eye-opener to see the possibilities

Yes - indeed, this is so complex, that my current mapping is a
One-to-many mapping with a aux "gender" table - so each customer would
add as many options as they want.
