pattern, a DBObject is typically a single table, and if I am building a
view out of, say six db tables, then I would typically first build six
DBOjects, then use something similar to the RegisterUser servlet to
build the logic, making different calls to the 6 different DBOjects. Am
I understanding the architecture correctly? Are there exceptions worth
noting for this basic level of app?

Additionally, I am having a difficult time finding documentation on how
the DBOjects isntantiates the auto-increment functions in mysql, or even
whether in fact it is better to keep that in the NextNumber class, such
as the JobHandler does?
