Servlets, Methodology, JDBC...
Is there any DB2 Servlets samples ?
Is there any metodology to develop using them ? Something like design
patterns to databases or a kind of UML for Databases ?
Of course, I'll use a ER to model, but what about the software
(application) process ?

Suggestions ?

Thanks in advance
